Which of the following structure represent meso-compound ?

Options

A.
B.
C.
D.

Explanation

To determine which of the given structures represents a meso compound, we need to understand the characteristics of meso compounds. A meso compound is a molecule that has multiple stereocenters but is superimposable on its mirror image due to an internal plane of symmetry.

### Step-by-Step Solution:

1. **Identify the Structures**: Examine the structures provided in the question. Look for compounds that contain stereocenters (chiral centers) which are typically carbon atoms bonded to four different groups.

2. **Count Stereocenters**: For each structure, count the number of stereocenters. A meso compound must have at least two stereocenters.

3. **Check for Symmetry**: For each compound with two or more stereocenters, check if there is an internal plane of symmetry. This means that one half of the molecule is a mirror image of the other half.

4. **Determine Superimposability**: Assess whether the compound can be superimposed on its mirror image. If it can, then it is a meso compound.

5. **Select the Meso Compound**: From the structures analyzed, select the one that meets the criteria of having stereocenters, an internal plane of symmetry, and being superimposable on its mirror image.

### Conclusion:
After analyzing the structures, the one that fits the criteria of a meso compound will be identified.
