Question

Which among the following is a/an infectious disease?

The correct option is B Diphtheria

Coronary thrombosis is the formation of a blood clot inside a blood vessel of the heart.
Diabetes mellitus is a chronic, lifelong condition in which there are high blood sugar levels over a prolonged period.
Hypertension is the increase in the blood pressure.

Therefore, the correct answer is option B.
