B.Dehydration
C.Revolution
D.dehydrohalogenation

Answer 1

Hint: Chirality can be understood as a property of asymmetry that can make two similar molecules non -superimposing images of each other. To put it in simpler terms, chirality can be understood as the property which forms a similar molecular structure that cannot be placed over one another to obtain the same molecule.

Complete Step-by-Step Answer:
Before we move forward with the solution of the given question, let us first discuss some important basic concepts.
Now, enantiomers can be explained as the chiral molecules that are mirror images of each other. Also, they are non – superimposable on one another. Now one special characteristic of enantiomers is that they always exist in pairs. The molecules in this pair are known as diastereomers. Diastereomers usually contain one chiral centre that renders the non - superimposable property to them. But then again, depending on the type of molecule, the number of chiral centres may be more. The two types of diastereomers are d and l, which stand for dextro and laevo. These tags define the direction in which the optical activity of the given enantiomer rotates.
Racemic modification can be understood as a mixture which contains equal quantities of both the dextro and laevo enantiomers. Because of this, the optical rotation caused by both the enantiomers gets cancelled out and it results in net zero optical activity. This process of separation of racemic modifications into d and l enantiomers is called Resolution.
Hence, Option A is the correct option

Note: It is noteworthy that, when enantiomers are mixed together, the rotation caused by a molecule of one isomer is exactly cancelled by an equal and opposite rotation caused by a molecule of its enantiomer.
