The answer is the letter c
Which type of cell might have been the first one to evolve and explain why this may have been the first.
The hypothesis that eukaryotic cells evolved from a symbiotic<span>
association of prokaryotes—endosymbiosis—is particularly well supported by studies of mitochondria and chloroplasts, which are thought to have evolved from bacteria living in large cells.</span>
Compare and contrast eukaryotic cells with prokaryotic cells.
Eukaryotic cells contain membrane-bound organelles, including a nucleus. Eukaryotes can be single-celled or multi-celled, such as you, me, plants, fungi, and insects. Bacteria are an example ofprokaryotes. Prokaryotic cells do not contain a nucleus or any other membrane-bound organelle.

Answer:
Option C, The cell membrane allows water to enter and leave the cell.
Explanation:
Options for the question are –
A. The cell membrane is an impermeable barrier that prevents water from entering the cell.
B. The cell membrane allows solutes to enter the cell, which causes the cell to shrink.
C. The cell membrane allows water to enter and leave the cell.
D. The cell membrane removes solutes from the environment.
Solution -
The cell membrane is semi permeable to water and some other substances. Whenever there is a difference in concentration or volume on the two sides of the membrane, either the solute or the solvent starts moving till equilibrium is reached. In few cases, the flow continues uninterrupted thereby increasing the cell size to its maximum extent and hence bursting it.
Hence, option C is correct
