Answer:
Option B, OH- accumulates on the inside of the membrane while H+ accumulates on the outside.
Explanation:
In electron chain reaction, the electrons move through a series of electron transporters thereby undergoing redox reactions. This leads to accumulation of hydrogen ion (H+) with in the matrix and hence development of concentration gradient that leads to diffusion of hydrogen ion out of the matrix and accumulation of OH- ion on the inner side of the matrix while passing through ATP synthase
Hence, option B is correct
