If {A}+ {B}+ {C}=\frac{\pi}{2}, then \sqrt{2} \cos (\frac{\pi}{4}- {A})+\sqrt{2} \cos (\frac{\pi}{4}- {B})+\sqrt{2} \cos (\frac{\pi}{4}- {C})+1=

Correct Answer is : 4√2cosA2cosB2cosC2

4 \sqrt{2} \cos \frac{ {A}}{2} \cos \frac{ {B}}{2} \cos \frac{ {C}}{2}

4 \cos \frac{A}{2} \cos \frac{B}{2} \cos \frac{C}{2}

4 \sin \frac{A}{2} \sin \frac{B}{2} \cos \frac{C}{2}

4 \sqrt{2} \sin \frac{ {A}}{2} \sin \frac{ {B}}{2} \cos \frac{ {C}}{2}
