Following the RBI's 1998 Working Group revision, NM1 (the narrowest new monetary aggregate, analogous to the old M1) is composed of: currency with the public, demand deposits with the banking system, and 'Other' deposits with the RBI.
Short-term time deposits of residents are NOT part of NM1 — they enter the broader aggregates NM2 (which adds short-term time deposits) and NM3 (the broadest, adding long-term time deposits and other items). Time deposits by their nature are less liquid than demand deposits and currency, which is why the narrowest aggregate excludes them.
(A), (B), and (D) are all genuine components of NM1; only (C) is excluded.
Therefore the answer is (C).
The trap: (D) 'Other' deposits with the RBI
'Other deposits with the RBI' sounds like an unusual, easily-overlooked category that students might assume is the 'odd one out' and therefore the excluded item, when in fact it IS a genuine (if small) component of NM1 — the real exclusion (time deposits) is a more substantial, commonly known monetary category that's easy to assume must be included given how central it is to overall money supply.
