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).

I'll never forget see his face,(A)/ his lively smile, his glittery (B)/eyes, everything will always (C)/remain in my memory.

Correct option is A

The error lies in part A. Here, ‘see’ must be changed with ‘seeing’. “forget” when is used as to explain that you have forgotten something, it must be followed by a gerund.
