Which is the popular street food in Mumbai?

Option B

Vada Pav is a vegetarian fast food dish native to the state of Maharashtra. The dish consists of a deep fried potato dumpling placed inside a bread bun (pav) sliced almost in half through the middle. It is generally accompanied with one or more chutneys and a green chilli pepper. Although it originated as cheap street food in Mumbai, it is now served in food stalls and restaurants across India. It is also called Bombay burger in keeping with its origins and its resemblance in physical form to a burger.
