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

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)& (B)` is incorrect

Text Solution

Verified by Experts

Correct (A): hcp and ccp are equally closest packed since space occupied in both `= 74%`
Correct (R): Both have `CN = 12`
