P1V1^n = P2V2^n.
(V1/V2)^n = P2/P1.
Take log on both sides,
n log (V1/V2) = log (P2/P1).
.: n= Option B.
(V1/V2)^n = P2/P1.
Take log on both sides,
n log (V1/V2) = log (P2/P1).
.: n= Option B.

I am not understanding this, please, derive this.

Derive it from poly-tropic process formula i.e. P1V1^n = P2V2^n.
