Parts of the following sentence have been given as options. Select the option that contains a grammatical error.
Mother said that / it was quite all right / for her to get upset / for scoring less.

Correct option is D

Option (d) contains an error.
In sentence "Mother said that it was quite all right for her to get upset for scoring less."
This mixes both expressions ( “quite right” + “all right”) in a way that feels redundant or awkward in formal grammar. Hence:
· You can say: ✔️ “It was quite right for her to get upset…” (meaning: it was justified) ✔️ “It was all right for her to get upset…” (meaning: it was acceptable)
❌ But “quite all right” tends to work only in casual or spoken English, meaning “completely fine,” which doesn't match the tone of being upset due to scoring less — an emotional reaction rather than a permitted action.
✅ Grammatical Rule:
Option (d) contains the error because “quite all right” is not idiomatic or precise for this context in standard written English. It’s better to use “all right” alone.
