Kaiser · Answer 1

B and C

Explanation:

A is not true. That is an entirely different atom

B is possible. The neutrons don't effect the atomic number or the place on the periodic table.

C is also correct. The nitrogen is just a little heavy.

D has too few protons. It is not part of the nitrogen family.
