Solution

The correct option is B False
Isobars:
Isobars are atoms with the same number of nucleons from different chemical elements.
The mass number is the same in isobars whereas the atomic number is different.
In the given elements ${}_{90}^{231}Z$ and ${}_{90}^{233}Z$ , atomic number is the same but the mass number is different.
Thus, these are isotopes, not isobars.
Hence, the given statement is false.
