C Correct answer
Explanation

Lactic acid accumulates in muscles during intense exercise when oxygen supply is insufficient for aerobic respiration. This buildup causes muscle fatigue, soreness, and the characteristic burning sensation. The other options - fumaric acid, maleic acid, and acetic acid - are not typically associated with muscle fatigue or exercise physiology.
