Which of the following compounds is an example of a meso compound?

Which of the following compounds is an example of a meso compound?

Step 1: Understand what a meso compound is. A meso compound has multiple chiral centers but is superimposable on its mirror image.
Step 2: Identify the compound in question, which is 2,3-butanediol.
Step 3: Check if 2,3-butanediol has chiral centers. It has two chiral centers at the 2nd and 3rd carbon atoms.
Step 4: Determine if 2,3-butanediol is superimposable on its mirror image. Draw the structure and see if you can overlay it on its mirror image.
Step 5: Conclude that since 2,3-butanediol can be superimposed on its mirror image, it is indeed a meso compound.
