Solution

The correct option is A Beadle and Tatum
In 1941, Beadle and Tatum studied a bread mold, Neurospora crassa. Neurospora can be cultured together with sugar, inorganic salts and the vitamin biotin. This fungus has a short life cycle, and reproduces sexually and replicates asexually—that is, sexual reproduction gives rise to spores.
