The correct option is
A Anaerobic respiration
Fermentation is a type of anaerobic respiration in which the breakdown of glucose takes place to release acids, alcohols and other gases in absence of oxygen. It takes place in the cytoplasm.
It involves glycolysis which is the breakdown of glucose to form pyruvic acid which can undergo two different pathways to form the lactic acid or ethanol and carbon dioxide.
So, the correct option is 'Anaerobic respiration'
