Answer 1

The correct option is D (A)- (III), (B)- (IV), (C)- (II), (D)- (I)

Agar is a natural polysaccharide (starch) product extracted from certain species of red algae like Gelidium, Gracilaria etc.

Biofertilizers are organisms that enrich the nutrient quality of soil. The main sources of biofertilizers are cynobacteria (blue-green algae). Dominant nitrogen-fixer blue-green algae are Anabaena, Nostoc etc.

Basidiomycota are filamentous fungi composed of hyphae, and reproduce sexually via the formation of specialized club-shaped end cells called basidia that normally bear external meiospores (usually four). It includes groups like Mushrooms, puffballs etc.

Saccharomyces cerevisiae contains several B vitamins. These include vitamin B1 (thiamine), vitamin B2 (riboflavin), vitamin B3 (niacin), vitamin B5 (pantothenic acid), vitamin B6 (pyridoxine), vitamin B7 (biotin), and vitamin B9 (folic acid).
Hence, option D is correct.
