Assertion (A): RNA is usually single-stranded.
Reason (R): RNA contains deoxyribose sugar.
A. Both A and R are true, but R is not the correct explanation.
B. A is false, but R is true.
C. A is true, but R is false.
D. Both A and R are true, and R is the correct explanation.
Answer: Option C
Solution (By JKExamLibrary)
RNA is typically single-stranded (A true), but it contains ribose, not deoxyribose. Deoxyribose is in DNA. Thus R is false.
