Error spotting (bank/SSC style): Choose the part (A/B/C) that contains a grammatical error — mark D if there is no error — 'He loved / none but / his neighbour's daughter. / No error.'

Given sentence parts (A–D)A. He lovedB. none butC. his neighbour's daughter.D. No error.

Concept/Approach (idiom 'none but')The phrase none but correctly means 'only'. The verb form and possessive (neighbour's) are standard. Hence, the sentence is grammatically sound.

VerificationParaphrase: 'He loved only his neighbour's daughter.' No structural or agreement error arises.

Common pitfallsMistaking 'none but' for a negative that needs subject–verb inversion or additional particles. It does not.

Final AnswerD — No error.
