Solution

The correct option is A

True


Just like water particles, electrons move at a quicker rate when there is a wider cross-section or area of cross-section available for their movement. The resistance of the conductor is inversely proportional to the cross-sectional area. So, as the cross-sectional area increases, the resistance decreases which results in an increased current.
