Option B, they negate each other
Explanation:
Electrical gradient force is more or less equal to the chemical gradient during an active transport. The number of electron produced during the establishment of chemical gradients, were transferred through the cellular circuit to produce electrical gradient of an equivalent amount in opposite path.
Thus, both electrical and chemical gradient are opposite to each other and hence they negate out each other.
