Solution

The correct option is C Assertion is correct but Reason is incorrect
A molecule which has no plane of symmetry is described as chiral. The carbon atom with the four different groups attached which causes this lack of symmetry is described as a chiral centre or as an asymmetric carbon atom. Also, molecules can be chiral without having a center of chirality (image of examples are attached). Trans-1,2 dimethyl cyclopropane is a chiral molecule.
