Choose the option that completes the sentence using the correct spelling. Doctors often treat two types of ______: viral and bacterial.

Explanation

The correct option is (b). Option (B) is the correctly spelt word. Correct spelling is: “pneumonia”. It is an infection that inflames the air sacs in one or both lungs, which may fill with fluid, causing cough, fever, and difficulty in breathing (Hindi meaning: निमोनिया). It can be caused by bacteria, viruses, or fungi, and hence “viral and bacterial” are valid classifications. Example: The doctor diagnosed him with pneumonia and prescribed medicines. Meanings of all the given options: Option A: Pnemonia – incorrect spelling; missing the correct “pneu-” sequence (गलत वर्तनी). Option B: Pneumonia – lung infection/inflammation of air sacs (निमोनिया). Option C: Pnumonia – incorrect spelling; missing “eu” after “pn” (गलत वर्तनी). Option D: Pneumonea – incorrect spelling; wrong ending “-nea” instead of “-nia” (गलत वर्तनी). So the correct answer is (b)
