A fatty acid that contains a chain of ten carbons and one double bond is termed a fatty acid. A. saturated, medium chainB. saturated, long chainC. monounsaturated, medium chainD. monounsaturated, long chain

C. monounsaturated, medium-chain fatty acid

Explanation:

Fatty acids are carboxylic acids and have hydrocarbon chains that are mostly four to 36 carbons long. A fatty acid with only single bonds but no double bonds is said to be a saturated fatty acid. The presence of one or more double bonds makes the fatty acids unsaturated ones.

A fatty acid with one double bond is a monounsaturated (mono = one) fatty acid. The fatty acids with a chain of 6 or 8 to 12 carbon atoms are said to be a "medium-chain" fatty acid. Therefore, a fatty acid that contains a chain of ten carbons and one double bond is a "monounsaturated, medium-chain fatty acid".
