Solution

The correct option is C Assertion is correct but Reason is incorrect
The tetrahedral molecule has no geometrical isomers, since all the bond angle is same ${109.5}^{0}$ , for geometrical isomerism, at least one band angle should be different, otherwise, orientation will not different to show isomerism.
Also, tetrahedral complexes have $s p^{3}$ hybridization.
Thus the Assertion is correct but the Reason is incorrect.
