Proton and Nuclear Magnetic Moments

Assertion (A): All protons have non zero magnetic moment.
Reason (R): All nuclei have non zero magnetic moment.
 
Both (A) & (R) are true and the (R) is the correct explanation of the (A)
Both (A) & (R) are true but the (R) is not the correct explanation of the (A)
(A) is true but (R) is false
Both (A) and (R) are false

Solution:

Protons possess intrinsic spin and thus a non-zero magnetic moment. So (A) is true. Nuclei with even numbers of both protons and neutrons (even-even nuclei) have zero net spin and zero magnetic moment. So (R) is false.
