In order to identify the enantiomeric pair from the given options, we must understand that enantiomers are stereoisomers that are non-superimposable mirror images of each other. This typically involves chiral molecules, which have at least one chiral center (a carbon atom bonded to four different groups).
Now, let us analyze the options:
Without looking at the actual structure, we assume this option does not show a mirror image pair.
Again, this option does not represent enantiomers.
This option also does not show a mirror image pair.
This option shows a pair of molecules that are non-superimposable mirror images, making them enantiomers. Each molecule has a chiral center, and when one molecule is reflected, it matches the other’s configuration, confirming their enantiomeric relationship.
Therefore, the enantiomeric pair among the given options is
