Solution

The correct option is A pH gradient and electro potential gradient
In proton pumps, positively charged protons create proton gradient across the membrane,proton gradient have 2 component i.e chemical and electrical.The chemical copmponent is proton concentration or pH gradient electric component is electric potential across the membrane ,resultingh net increase of positive charges on cytosolic side.
So, the correct option is 'A'.
