Answer:
A- The current is constant and is directed from a to b
Step-by-step explanation:
when the resistance value becomes high, then,the current flow will decrease and on the other side the resistance value is low, the current flow is going to be increase when the potential difference remains constant in the circuit.
Also, the resistance is going to be zero, thus, the current flow is going to remain constant if the potential difference remains has constant.
Therefore, the statement which consistent with the situation is the current is constant and is directed from a to b.
