Assertion : Compressibility factor (Z) for non-ideal gases can be greater than 1.
Reason : Non-ideal gases always exert higher pressure than ideal gases under identical conditions expected.

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) and (R) are incorrect.
