Answer #1

To keep the animal cells live in a culture dish, the important substances are NaCl, pH, and water. These substances maintain the osmolarity of the animal cells. The substance that is not found to be critical for their living is nucleotides. It is because nucleotides are needed in DNA replication, not to keep the animal cells alive in culture medium.

Hence, the correct option is (a)

About the incorrect options-

The other substances are critical for keeping the animal cells alive in culture medium.

Hope it helps
