Correct answer: D

Explanation

The correct answer is D, as a bitmap is used to track the number of blocks that are heavily utilized, which is crucial for efficient snapshot management. Option A is incorrect because it refers to tracking changes rather than utilization. Options B and C are also incorrect as they deal with read and write addresses, which are not the primary function of a bitmap in snapshot creation.
