Q1. Spirulina is a good source of:
A Fat
B Vitamin C
C Carbohydrate
D Protein Correct
Explanation
Spirulina is a blue-green cyanobacterium used as a dietary supplement because it is especially rich in protein. Its dry biomass contains a high proportion of easily digestible protein, which is why it is promoted in nutrition and food-security contexts. Fat is present only in a limited amount and is not its main nutritional identity. Vitamin C is not the standard reason Spirulina is cited in basic science questions. Carbohydrate is also present, but Spirulina is not primarily known as a carbohydrate-rich food. Therefore, protein is the correct source asked here.
