Solution

The correct option is D $_{6}^{14} C$ and $_{7}^{14} N$ have the same mass numbers, but therefore they are isotopes of each other.
Isotopes have the same atomic number and different mass number
whereas Isobars have the same mass number and different atomic number.
Thus, $_{6}^{14} C$ and $_{7}^{14} N$ are isobars of each other.
Thus statement given in option D is false.
