A metallic resistor is connected across a battery. If the number of collisions of free electrons with the lattice is somehow decreased in the resistor, the current will

$\begin {array} {1 1} (A)\;Increase & \quad (B)\;Decrease \\ (C)\;Remain \: constant & \quad (D)\;Become\: zero \end {array}$

If numbers of collisions are decreased, the resistance is decreased.
Ans : (A)
