Q. 4

B is incorrect because the passage concludes that "non-genetic material in the germ plasm" (that would be an unfair trick to say non-genetic but then the answer relies on genes) and also because mitochondrial DNA only codes for about 37 genes, all of which are essential for normal mitochondrial function. The idea that the determination of an entire cell would rest in an organelle that contains very few genes that in fact carry codes for itself would be unlikely.

Genetic material is used to store the genetic information of an organism. There does exist some viruses that use RNA as genetic material. However, for all currently known living organisms, the genetic material is almost exclusively DNA.

The point of the explanation was only to say that RNA can be genetic material in some viruses. The passage of course is about eukaryotic cells which limits the discussion of genetic material to DNA. To be clear, the passage states that non-genetic material in the germ plasm is responsible for germ cell formation. This is why RNA in eukaryotes can be considered as an answer. Finally, the explanation provides the reasoning why RNA and proteins must be the correct answer.
