This is an Assertion and Reason type question. This question consists of two statements, namely, Assertion (A) and Reason (R). Select the most suitable option considering the Assertion and Reason. Assertion (A): SMS is an acronym for Smart Message Service. Reason (R): SMS is the most common technology for delivering short, concise, and important messages quickly.
- A.
Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of Assertion (A).
- B.
Both Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation of Assertion (A).
- C.
Assertion (A) is true, but Reason (R) is false.
- D.
Assertion (A) is false, but Reason (R) is true.

Show answer & explanation
Correct answer: D
Concept: In an Assertion–Reason item, judge the truth of Assertion (A) and Reason (R) independently first. Only when BOTH are true do you go on to ask whether R is the correct explanation of A; if either statement is false, the explanatory question does not arise and the option must instead match the actual true/false pattern of A and R.
Application:
Evaluate Assertion (A): SMS is standardised (ETSI/3GPP) as “Short Message Service”, not “Smart Message Service”. So Assertion (A) is FALSE.
Evaluate Reason (R): SMS is in fact the most widely used mobile technology for sending short, concise, time-sensitive text messages — this is an accurate, independently true statement about how SMS is used. So Reason (R) is TRUE.
Cross-check: A false Assertion paired with a true Reason is a distinct pattern from “both true” or “A true, R false” — re-reading each statement on its own confirms neither truth value depends on the other, so the pairing (A false, R true) is internally consistent and is the pattern that matches the facts here.
