Question

Which isotope of carbon is isobaric with naturally occurring nitrogen element?

• A. C–12
• B. C–14
• C. C–16
• D. C–18

The correct option is C

C–16

Isobars have the same atomic mass number and different atomic numbers. C-14 is an isotope of carbon and has the same number of nucleons as that of naturally occurring nitrogen. Thus, they are isobars.
