Solution

The correct option is B racemisation
The process of converting one enantiomer of an optically active compound into racemic mixture is called racemisation.
Thus when we start from d-glyceraldehyde and obtain d,l-glyceraldehyde, it is called racemisation.

Similarly, when we start from l-glyceraldehyde and obtain d,l-glyceraldehyde, it is called racemisation.

When a racemic mixture is separated into individual enantiomers, we call it as resolution.

If a pure stereoisomer is converted into its enantiomer, we call it as inversion.

Epimerisation is a process of obtaining an epimer by converting an asymmetric center in compound containing several asymmetric centers.

Option D is correct.
