Match the following:

Methods of spread of infection	Example (Disease)
a. Inhalation	1. Arbovirus
b. Ingestion	2. Toxoplasmosis
c. Inoculation	3. Food poisoning
d. Congenital	4. Mumps

Choose the most appropriate option from below :

Answer: C

The correct matching is a-4, b-3, c-1, d-2.

Inhalation: mumps spreads by respiratory droplets.
Ingestion: food poisoning comes from eating contaminated food.
Inoculation: arboviruses such as dengue are inoculated into the skin by the bite of an arthropod vector.
Congenital: toxoplasmosis passes from mother to fetus across the placenta.

The other codes fail on at least one of these: a-1 makes arboviruses airborne, and b-3 with c-2 sends toxoplasmosis in through the skin.
