Define incubation period.

Explanation:
The incubation period is the interval from the moment of infection to the onset of first symptoms. It ends when symptoms begin and does not refer to how long you might be contagious (that’s a different concept, the latent period) or to immunity development. This option identifies the definition precisely by describing the time leading up to symptom onset—the period before symptoms develop in the host. For example, if exposure occurs on day 0 and symptoms appear on day 5, the incubation period is five days.
