Read the sentence to find out whether there is any grammatical or idiomatic error in it. The error, if any, will be in one part of the sentence. The corresponding letter of that part is the answer. If the given sentence is correct as it is, then choose option ‘No error’ as the answer response. (Ignore errors of punctuation, if any).

A thorn from one (A)/ of the prickly bushes pushed (B)/ through the boy’s shoe (C)/ and into his food (D)/no error (E).

Correct option is C

The error lies in part (D) of the sentence.
This phrase is incorrect because "food" is misspelled and doesn't make sense in the context of the sentence. The correct word should be "foot," which is where the thorn went into.
Hence, the correct sentence formed will be “A thorn from one of the prickly bushes pushed through the boy’s shoe and into his foot”
