Margie is creating and testing a Web form that includes an email field, a Web address field, and a zip code field, among others. When she has a few co-workers test the form, she finds they often enter the email address in the Web address field by mistake, and sometimes enter too many or too few numbers in the zip code field. She doesn't want to use a pattern expression because she says it's too complicated. What other input types can Margie use?

a) type=text for email, type=url for Web address, and type=number for zip code.
b) type=email for email, type=text for Web address, and type=tel for zip code.
c) type=url for email, type=email for Web address, and type=text for zip code.
d) type=text for email, type=text for Web address, and type=text for zip code.
