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).

She chose to take (A)/ the scenic route (B)/ instead the highway (C)/ to enjoy the beautiful countryside. (D)

Correct option is C

The error in part (C) of the sentence is related to the use of the word "instead." Here's the grammatical explanation:
"Instead" is an adverb that is used to indicate a choice or preference between two options. It is typically used to show that one option is chosen over another. In the sentence, the correct placement of "instead" is before "the highway," as in "instead of the highway." This structure correctly conveys the idea that the scenic route was chosen as an alternative to the highway.
So, the corrected sentence is: "She chose to take the scenic route instead of the highway to enjoy the beautiful countryside."
