A tester is used to check the conduction of electricity through two liquids, labelled A and B. It is found that the bulb of the tester glows brightly for liquid A while it glows very dimly for liquid B. From the above observations one can conclude that:

Liquid A is a better conductor than liquid B.

Solution

The correct option is A
Liquid A is a better conductor than liquid B.

Liquid B is a weaker conductor of electricity than liquid A, so bulb glows dimly in the second case.
