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. You would conclude that

(A) liquid A is a better conductor than liquid B.
(B) liquid B is a better conductor than liquid A.
(C) both liquids are equally conducting.
(D) conducting properties of liquid cannot be compared in this manner.
