Which one of the following is not true about the membrane invagination hypothesis?

Explanation

The membrane invagination hypothesis describes the process by which the internal membranes of eukaryotic cells, such as the endoplasmic reticulum and nuclear envelope, evolved through the invagination of the plasma membrane of a prokaryotic ancestor. This hypothesis supports the formation and specialization of membranes into complex organelles. Option D, 'Second membrane dissolves,' is incorrect as it contradicts the hypothesis's emphasis on membrane formation rather than dissolution. Options A, B, and C accurately describe aspects of the hypothesis, focusing on the creation and specialization of internal membranes.
