Text Solution

Verified by Experts
The correct answer is:
A
Step 1: Identify the physical quantities represented in Column I with their dimensions.
1. Curie (Ci) is a unit of radioactivity. It denotes the number of decays per second, hence its dimension is related to time.
Step 2: Analyze the units in Column II for their relation to the provided quantities.
The (I) G corresponds to Curie for radioactivity measurements.
Therefore, the correct match is (I) G corresponding to Curie.
