Solution

The correct option is A true, false
12C is an isotope of 14C.

As isotopes are variants of a particular chemical element that differ in neutron number but have the same number of protons.

12C has 126=6 neutrons.

14 has 146=8 neutrons.
Hence, the statement I is true but the statement II is false.
