Answer : d
Hints & Solution
(d) Spallanzani’s experiment: He boiled the meat and vegetables for more than an hour to prepare broth and placed them in open and sealed flasks. The maggots of housefly developed in the open flasks but did not appear in sealed flasks. This disapproved the theory of spontaneous creation. (Th. of abiogenesis).
