Correct option is A
An alicyclic compound is an organic compound that contains a ring structure but is not aromatic. Cyclopropane is an example of an alicyclic compound because it has a three-membered ring structure made of carbon atoms,
is a saturated alicyclic compound, which means it has only single bonds between carbon atoms, unlike cycloalkenes that contain double bonds.
Alicyclic compounds can be open or closed rings, and in Cyclopropane, the three carbon atoms form a closed ring.
These compounds can have varied structures—saturated or unsaturated—and can be used in various chemical and industrial processes.
Cyclopropane is an unstable compound due to angle strain in the three-membered ring, which causes it to be highly reactive.

Isobutane: Isobutane is a branched-chain hydrocarbon.
Acetic acid: This is a carboxylic acid, not an alicyclic compound.
Ethane: This is a straight-chain alkane.
