Question

what is the surface area of a cell?
how many nutrients are needed in the cell
the amount of dna contained inside the cell
the amount of workable space that the cell has available for exchange

Explanation:

The surface - area of a cell is related to the amount of workable space available for exchange of substances like nutrients, gases, and waste products across the cell membrane. It is not directly related to the amount of nutrients needed (which depends on cell's metabolic rate), nor the amount of DNA inside the cell.

Answer:

the amount of workable space that the cell has available for exchange
