A cyclic compound that contains only single bonds is classified as:

The correct option is Saturated.

To understand why this is the correct classification, let us break down the terms used in organic chemistry to classify hydrocarbons and organic compounds:

1. Saturated vs. Unsaturated Compounds:
- A saturated compound is one that contains only single bonds between carbon atoms. In these molecules, each carbon atom is bonded to the maximum possible number of hydrogen atoms (or other atoms), meaning the carbon atoms are "saturated" with bonds. Since the question specifies that the cyclic compound contains only single bonds, it falls under the category of a saturated compound.
- An unsaturated compound contains at least one double or triple bond between carbon atoms (such as alkenes or alkynes), which prevents the carbons from being bonded to the maximum number of hydrogen atoms.

2. Aliphatic Compounds:
- While cyclic compounds with single bonds (like cyclohexane) are technically classified as alicyclic (a subset of aliphatic compounds), the term "aliphatic" is a very broad category that includes both open-chain (acyclic) and cyclic structures, and can include both single, double, or triple bonds. Thus, "Saturated" is the most specific and accurate description for a compound containing only single bonds.

3. Aromatic Compounds:
- Aromatic compounds contain a special type of cyclic, planar ring structure with alternating double bonds (delocalized $\pi$ electrons) that follow Hückel's rule (like benzene). Since the compound in the question contains only single bonds, it cannot be aromatic.

Therefore, a cyclic compound containing only single carbon-carbon bonds is classified as a saturated compound (specifically, a cycloalkane).
