Correct answer: B
Explanation
The correct answer is option 2 i.e. Diphtheria.
A serious contagious bacterial infection that primarily affects the mucous membranes of the nose and throat is Diphtheria. It is caused by the bacterium Corynebacterium diphtheriae and spreads through respiratory droplets from coughing or sneezing. Symptoms include sore throat, fever, swollen glands, and a thick gray coating in the throat that can obstruct breathing. Diphtheria can lead to severe complications if untreated. Vaccination (DPT vaccine) is the most effective way to prevent this life-threatening infection.
