1. the number of replicating cells to the number of active cells.
2. the number of non-replicating cells to the active cells.
3. the number of replicating cells to the number of resting cells.
4. the number of non-replicating cells to the number of resting cells.

Rationale 1: This is not the ratio as it relates to the growth fraction.
Rationale 2: This is not the ratio as it relates to the growth fraction.
Rationale 3: The growth fraction is a measure of the number of cells undergoing mitosis in a tissue. It is a ratio of the number of replicating cells to the number of resting cells.
Rationale 4: This is not the ratio as it relates to the growth fraction.
Global Rationale: The growth fraction is a measure of the number of cells undergoing mitosis in a tissue. It is a ratio of the number of replicating cells to the number of resting cells. The other options are not related to growth factor.
