Correct option is B
The relationship in each pair:
Restaurant - Chefs: Chefs work in a restaurant, providing a service (cooking food).
Theatre - Movies: Movies are shown in a theatre, but they do not work there; they are the product being presented.
Hospital - Doctors: Doctors work in a hospital, providing medical services.
School - Teachers: Teachers work in a school, providing educational services.
In three pairs (Restaurant - Chefs, Hospital - Doctors, and School - Teachers), the second item is a person or group providing a service at the place mentioned. However, in Theatre - Movies, movies are not people providing a service; they are the content being shown.
Correct Answer: (b) Theatre – Movies.
