Solution

The correct option is C Assertion is correct but Reason is incorrect
In case of a short-circuit batter, the external resistance R will be zero. thus, current $I = \frac{E}{r} \neq 0$ where $E =$ emf of batter and $r =$ internal resistance of battery.

Terminal voltage, $V = I R = I (0) = 0$ as $R = 0$ .
