b)I couldn't find my hat nowheres.
c)I couldn't find my hat anywhere.
d)I couldn't find my hat anywheres

I'll be glad to check your answer.

Right!

The correct sentence written in standard English is:

c) I couldn't find my hat anywhere.

To identify the correct sentence, we need to look for grammatical errors, such as the use of double negatives or improper word choice. In choice a), there is a double negative ("I couldn't find my hat not anywhere") and in choice b), the word "nowheres" is grammatically incorrect. The correct choice is c) because it does not contain any grammatical errors and uses the word "anywhere" correctly. Choice d) is also incorrect because "anywheres" is not a proper word in standard English.
