Answer:

d. While there are some competing theories on the origin of the nucleus, neither theory discussed in the text really explains the origin of the nucleus.

Explanation:

The nucleus is found in eukaryotes in which the genetic material is enclosed. Some scientists say that the nucleus is evolved from mycoplasma which is a prokaryote who was engulfed by an amoeboid cell.

Some say that the nucleus is originated from archaea which were phagocytosed by bacteria. So there are some competing theories that tell about the origin of the nucleus but do not have proper evidence to explain the origin of the nucleus. So the correct answer is d.
