Solution

The correct option is B Diphtheria

Diphtheria is an infection caused by the bacterium Corynebacterium diphtheria. Symptoms include a sore throat, fever, barking cough, a grey or white patches develop in the throat. Diphtheria is usually spread between people by direct contact or through the air. It may also be spread by contaminated objects.

  • The bacterium produces a toxin called diphtheria toxin. This toxin damages tissue in the immediate area of infection usually, the nose and throat (air passage).

  • The semisolid material which forms a tough membrane over air passage is called the mucous membrane. The toxin damages the mucous membrane and causes the oozing of mucus.

  • So, the correct answer is 'Diptheria'.
