Correct answer: C

The correct answer is :

Option C : Both Statement I and Statement II are correct.

Here's why :

Statement I : In bacteria, the mesosomes are indeed formed by the extensions of the plasma membrane into the cytoplasm. They are typically observed as invaginations of the plasma membrane.

Statement II : Mesosomes in bacteria are thought to assist in several cellular processes including DNA replication, distribution of DNA during cell division, respiration, and cell wall formation. Hence, this statement is also correct.
