Correct Answer: Option (D) — 1, 2 and 3

Concept & Option Breakdown

Standard Reference Verified

Viruses are obligate intracellular parasites that infect all cellular forms of life.

  1. Viruses that infect bacteria are known as bacteriophages.
  2. Viruses that infect fungi are known as mycoviruses (mycophages).
  3. Viruses that infect plants include economically significant plant pathogens like Tobacco Mosaic Virus (TMV).
Elimination Heuristic & Exam Approach

In broad biological capability questions involving modal verbs like 'can infect', absolute exclusions rarely hold true in nature. Broad possibility statements covering major taxonomic domains are typically all correct.
