(a)

(b)

(c)

Short answer

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

Step-by-step solution

Meso compounds

Meso compounds are those which contain two or more two chiral centers. The optical activity of meso compounds is inactive, and their mirror images are superimposable. A plane of symmetry is present between the two chiral centers.

The meso form of the molecule (a)

(a) The meso form of the molecule is formed by drawing a plane of symmetry inside the molecule. These are superimposable mirror images, and it contains two chiral centers, one with R and the other with an S configuration.
