Question. His hair is grey with age .
Need to know the sentence is correct or not if wrong then want to know the correct answer

Dear student,

Here is the answer:

His hair is grey with age.

This sentence is incorrect as the word "grey " is used as a verb and not at a colour. Thus the correct sentence is:

a​​) His hair has greyed with age. (Here grey works as a verb. It means his hair has turned grey as he became old)
