An example for a saturated fatty acid, present in nature is
Option (d)
Oleic acid −C17H33COOH, linoleic acid −C17H31COOH, linolenic acid −C17H29COOH,palmitic acid −C15H31COOH. Saturated monocarboxylic acids form a homologous series which has a general formula −CnH2n+1COOH or −CnH2nCOOH. Only palmitic acid follows this.
