Explanation:

To determine the correct order of the pathogenesis of the common cold, we analyze the stages:

1. Inoculation: The virus (e.g., rhinovirus) enters the body (e.g., via nasal mucosa).
2. Incubation: The virus replicates and spreads, with no symptoms yet.
3. Symptoms: Early signs (e.g., runny nose, sneezing) appear as the immune system reacts.
4. Full - blown illness: Symptoms peak, and the body fights the infection more intensely.

Option b is incorrect because symptoms occur before the full - blown illness. Option c is incorrect as inoculation (exposure to the pathogen) must come before incubation. Option d is incorrect as symptoms and full - blown illness follow inoculation and incubation. Only option a follows the logical sequence of inoculation (exposure) → incubation (viral replication without symptoms) → symptoms (early signs) → full - blown illness (peak symptoms).

Answer:

a. inoculation, incubation, symptoms, full - blown illness
