The given sentence is divided into three segments. Select the option that has the segment with a grammatical error. If there is no error, select 'no error' as your answer.
Ameya won't eat any junk food at all.

Correct option is B

Option (b) contains no error.
The sentence is grammatically correct. Won’t (= will not) properly takes a bare infinitive ( eat). In negative contexts, any is the appropriate determiner (a negative-polarity item), and at all is a standard intensifier used with negatives to add emphasis. Word order and subject–verb agreement are also correct.
Grammatical rule used:
· After modal verbs (will/would/can/could, etc.), use the bare infinitive (base form) of the verb.
· Any commonly appears in negative statements, questions, and conditionals.
· At all is used to intensify negation or questions.
Example:
· She won’t eat any sweets at all during her diet.
Information booster:
· Any can appear in affirmatives with a “free choice” sense (e.g., Take any seat you like), but here the negative context (won’t) licenses any in its usual sense.
