angina
arteriosclerosis
atherosclerosis

Explanation:

1. An epidemic is a disease outbreak in a specific region, while a pandemic spreads across much of the world. Endemic refers to a disease regularly found in a particular area, and plague is a specific type of infectious disease. So a disease that spreads to much of the world is a pandemic.
2. Antibiotics are ineffective against viral infections. Taking them for viral infections can contribute to antibiotic - resistance. Using antibiotics only when prescribed, not sharing them, and taking them for the full recommended time are good strategies to reduce resistance.
3. Angina is chest pain due to reduced blood flow to the heart. Arteriosclerosis is the hardening and thickening of artery walls. Atherosclerosis is a type of arteriosclerosis where plaque builds up in the arteries. The disease where artery walls thicken, harden and become inflexible is arteriosclerosis.

Answer:

1. B. pandemic
2. B. taking antibiotics for viral infections
3. B. Arteriosclerosis
