If b^{-} = 2i^{-}-j^{-}-k^{-}, a^{-} = 3i^{-}+4j^{-}-5k^{-} and b^{-}\times(a^{-}\timesb^{-}) = {a^{-}-kb^{-}}/l then k/{l|b^{-}|} is

Correct Answer is : the orthogonal projection of −a on −b and equal to 7√6

the orthogonal projection of b^{-} on a^{-} and equal to 7/\sqrt50

the orthogonal projection of a^{-} on b^{-} and equal to 7/\sqrt6

the orthogonal projection of b^{-} in the direction perpendicular to a^{-} and equal to 5/3

the orthogonal projection of a^{-} in the direction perpendicular to b^{-} and equal to 752/3
