Divide the whole sequence into group of words of 4, 2 and 4 so in the input the First group will be- Smile Nile Style Mile Second group will be - Shine Wine Third group will be - Mine Swine Bovine Feline In step 1 the 1 and 2 of Third group are exchanging their position with the 3 and 4 respectively i.e. Mine Swine are exchanging their position with Bovine Feline respectively with everything else constant therefore step 1 is- Smile Nile Style Mile Shine Wine Bovine Feline Mine Swine In step 2 the 1 and 2 of First group are exchanging their position with the 3 and 4 respectively i.e. Smile Nile are exchanging their position with Style Mile respectively with everything else constant therefore step 2 is- Style Mile Smile Nile Shine Wine Bovine Feline Mine Swine In step 3 the 1 and 2 of Second group are exchanging their position i.e. Shine is exchanging it's position with Wine with everything else constant therefore step 3 is- Style Mile Smile Nile Wine Shine Bovine Feline Mine Swine In step 4 the 1 and 2 of First group are exchanging their position i.e. Style is exchanging it's position with Mile , 3 and 4 of First group are exchanging their position i.e. Smile is exchanging it's position with Nile and Similarly the 1 and 2 of Third group are exchanging their position i.e. Bovine is exchanging it's position with Feline , 3 and 4 of Third group are exchanging their position i.e. Mine is exchanging it's position with Swine with the positions of Shine and Wine remaining same therefor step 4 is- Mile Style Nile Smile Wine Shine Feline Bovine Swine Mine In step 5 the 1 and 2 of First group are exchanging their position with the 3 and 4 respectively i.e. Mile Style are exchanging their position with Nile Smile respectively and the 1 and 2 of Third group are exchanging their position with the 3 and 4 respectively i.e. Feline Bovine are exchanging their position with Swine Mine respectively with everything else constant therefor step 5 is- Nile Smile Mile Style Wine Shine Swine Mine Feline Bovine In step 6 the 1 and 2 of Third group are exchanging their position with the 3 and 4 respectively i.e. Swine Mine are exchanging their position with Feline Bovine respectively with everything else constant therefor step 6 is- Nile Smile Mile Style Wine Shine Feline Bovine Swine Mine In step 7 the 1 and 2 of First group are exchanging their position with the 3 and 4 respectively i.e. Nile Smile areexchanging their position with Mile Style respectively with everything else constant therefor step 7 is- Mile Style Nile Smile Wine Shine Feline Bovine Swine Mine As can be observed the pattern is repeating therefore step 8 will be Mile Style Nile Smile Shine Wine Feline Bovine Swine Mine step 9- Style Mile Smile Nile Shine Wine Bovine Feline Mine Swine step 10- Smile Nile Style Mile Shine Wine Mine Swine Bovine Feline step 11- Smile Nile Style Mile Shine Wine Bovine Feline Mine Swine step 12- Style Mile Smile Nile Shine Wine Bovine Feline Mine Swine step 13- Style Mile Smile Nile Wine Shine Bovine Feline Mine Swine step 14- Mile Style Nile Smile Wine Shine Feline Bovine Swine Mine As can be observed from steps 12-14 option D is not present Therefore the answer is option 'D'
