I only
B
I and II
C
I and III
D
III only
Correct answer: (a) I only
Explanation
- A
I only
I only. RTGS settles continuously; NEFT is batched (even if batches are frequent).
- B
I and II
I and II. Inward RTGS is not a customer charge in RBI’s published tariff in the way II states.
- C
I and III
I and III. Both RTGS and NEFT have been extended toward 24x7. III’s ‘only RTGS is restricted’ fails.
- D
III only
III only. Drops the settlement-speed line, which holds.
Summary. Official key is (a) I only. RTGS is real-time; NEFT settles in batches. Inward RTGS is not charged to the customer in the same way, and both systems now run long hours — so II and III fail. (c) keeps III.
