Both (a) and (b)
Respiration in Ascaris is both anaerobic and aerobic. It occurs in different conditions.

The main fatty acids which are produced include valerianic butyric and caproic acids. These are excreted through cuticle and these impart a characteristic smell like that of a canned pineapple.
