One of the statements below contains a word used incorrectly or inappropriately. Choose the option which has the incorrect or inappropriate usage of the word.

The word ring appears in all four sentences, but its meaning varies depending on the context.

Option A uses the word ' ring' in the clause 'blue stone on her ring' , referring to the ornament/jewellery ring. 

Option B uses ring them up correctly, meaning to call someone on the phone.

In Option C, ring is used incorrectly. The sentence says, “their mother told them to ring their clothes first,” where ring should be wring, meaning to squeeze water out of wet clothes.

Option D uses formed a ring correctly, meaning to encircle or surround something.

Option C is therefore the correct answer.
