Answer 1

The correct option is D A, B and D

Prions are small proteinaceous substances. Their sizes are even smaller than viruses. They neither contain DNA not do they contain RNA. So, option C is the incorrect pair.

Apart from this, option A is correct as rhizopus is the fungi over bread mould. Spirogyra is known as pond scum. Mycoplasma is a moneran.

So, option D " A, B, and D are correct" is the right answer.
