  • • at least one 4-card major
conditions
8+ HCP, anyOf(2)
why

Opener may have a 4-card major that 1NT hid. A 4-4 major fit plays a trick better than NT, so we ask before committing. 2♣ is chosen because it wastes the least space.

what happens next

Opener rebids 2♦ (no 4-card major), 2♥ (4+ hearts), or 2♠ (4+ spades, denies hearts).
