The correct option is D Disease : Pneumonia, Causative Organisms : Streptococcus pneumoniae, Mode of Infection : Droplet infection

Pneumonia is an inflammatory condition of the lung affecting primarily the microscopic air sacs known as alveoli. Pneumonia can be caused by a variety of viruses, bacteria, and sometimes fungi. Pneumococcal pneumonia is caused by bacteria, called Streptococcus pneumoniae, which is also called pneumococcus. Pneumococcus is spread through contact with people, who are ill or who carry the bacteria in their throat. One can get pneumococcal pneumonia from respiratory droplets from the nose or mouth of an infected person. It is common for people, especially children, to carry the bacteria in their throats without being sick.
