Assertion (A) : `hcp` is more closely packed than ccp.
Reason (R ) : `hcp` has a `CN` of `12`, whereas ccp has a `CN` of `8`.

Options

A. If both `(A)` and `(R)` are correct, and `(R)` is the correct explanation of `(A)`
B. If both `(A)` and `(R)` are correct, but `(R)` is not the correct explanation of `(A)`
C. If `(A)` is correct, but `(R)` is incorrect.
D. If both `(A)` is incorrect but `(R)` is correct.

Explanation

To solve the question, we need to analyze the assertion and the reason provided:

**Assertion (A):** `hcp` is more closely packed than `ccp`.

**Reason (R):** `hcp` has a `CN` (coordination number) of `12`, whereas `ccp` has a `CN` of `8`.
