(a)

(b)

(c)

Short answer

(b) The meso form of the given molecule is,

Step-by-step solution

Plane of symmetry

A plane of symmetry is an imaginary type of plane, and it passes through a molecule in such a way that it is a mirror image of each other.There are various planes like dihedral, horizontal, and vertical symmetry planes.

The meso form of the molecule (b)

(b) The meso form of the molecule is obtained by drawing the plane of symmetry from a molecule, and on each side of the symmetry plane chiral centers are present. The left side has a chiral center with an R configuration, and on the right, the chiral center has an S configuration.
