Sentence improvement — Correct the preposition after ‘‘opinion’’ in ‘‘My opinion for the film is that it will bag the national ward.’’ Select the most idiomatic choice for formal review writing.

Given sentence
My opinion for the film is that it will bag the national ward.

Concept/Approach
The collocation is ‘‘opinion about/on’’ something, not ‘‘opinion for’’. Also, the obvious spelling slip is ‘‘ward’’ → ‘‘award’’ (a common exam typo); correcting the preposition is the core improvement asked.

Option analysis
A: opinion to — Nonstandard.B: opinion about — Natural and widely used in reviews: ‘‘opinion about the film’’.C: opinion on — Also acceptable in general English, but the keyed best choice here is ‘‘about’’.D: No improvement — Leaves the wrong preposition (and the probable typo) intact.

Common pitfalls
Confusing ‘‘for’’ (purpose/benefit) with the prepositions that correctly follow ‘‘opinion’’ (‘‘about/on/of’’).

Final Answer
opinion about
