The correct option is B alcohol, lactic acid or similar compounds
Anaerobic respiration is the process of the release of energy in an enzymatically-controlled stepwise incomplete (partial) degradation of organic food without O2 being used as a terminal electron acceptor. Therefore, the end products are never completely inorganic.
In case of microorganisms, the term fermentation is more commonly used instead of anaerobic respiration. The common types of fermentation are alcoholic fermentation (where ethanol or ethyl alcohol is the end product) and lactic acid fermentation (when lactic acid is the end product).
Fermentation can be defined as the anaerobic breakdown of carbohydrates and other organic compounds into alcohols, organic acids etc. with the help of microorganisms or their enzymes.
