You’re reviewing the campaigns of a new client who wants to better promote his child daycare facility to parents researching childcare on their mobile devices. Currently, his ads include generic text about childcare. To optimize his ads for mobile, you might create an ad with: A. the computer version of the facility’s website as the landing page, and a headline and description text that encourages people to sign up for the facility’s newsletter

B. a headline and description text that includes a customer testimonial, and uses the previous visits automated ad extension to let people see when they last visited the client’s website

C. the mobile version of the facility’s website as the landing page, and uses an interactive video showing current students and teachers reading together

D. a headline and description text that encourages people to sign up for a tour, and uses location extensions so they know where the client’s business is located
