What am I if I am brown on outside and yellow inside?

The correct answer to this question is B.

In appearance, the pineapple has a short, brown, stocky stem with tough, green, waxy leaves. It has 30 or more long, narrow, fleshy, trough-shaped leaves with sharp spines along the margins that are 30 to 100 cm (1.0 to 3.3 ft) long, surrounding a thick stem. The sweet, yellow flesh and juices of the pineapple are used in cuisines around the world.

In many tropical countries, pineapple is prepared and sold on roadsides as a snack. Raw pineapple is a rich source of manganese and vitamin C, but otherwise contains no essential nutrients in significant quantities.
