Question

Which sentence uses the word who’s correctly?

A.) Calling from the kitchen, my father said, “Who’s turn is it to empty the dishwasher?”
B.) Brenda, who's car is 52 years old, regularly participates in vintage car rallies.
C.) The lady who’s wearing the black dress is the wife of Mr. Darcy.
D.) Who’s car is parked in the no-parking area?

Answer 1

C.) is the correct use of "who's." "Who's" is a contraction of who and is. In each sentence, instead of saying who's, say who is.
(ex. "Who is turn is it..." doesn't sound right.).
The other three sentences are incorrect; they need "whose" instead which is a determiner or pronoun showing possession.
