Assertion (A): Viruses are considered obligate intracellular parasites. Reason (R): They lack their own metabolic machinery and require a host cell to multiply.
A. A is false, but R is true.
B. A is true, but R is false.
C. Both A and R are true, and R is the correct explanation of A.
D. Both A and R are true, but R is not the correct explanation.
Answer: Option C
Solution (By JKSSB Mock Tests)
Viruses are non-living outside a host; they cannot carry out metabolic processes or reproduce independently. They hijack the host cell's machinery to replicate. Thus, they are obligate intracellular parasites. The reason correctly explains the assertion.
