Answer 1

Answer: (D)

The virus causing common cold can leave the body of infected people through the mucus.

Common cold is a highly contagious viral infection. The virus affects the whole upper respiratory tract, producing a swollen, inflamed lining to the nose, throat. Mucus from the nose is loaded with viruses, and the air breathed, coughed or sneezed out by an infected person may infect others in near vicinity. Thus option D is the correct answer.
