Which explains why a lima been is a dicot seed?
A
one embryo in the seed
B
one food storage area in the seed
C
two embryos in the seed
D
two food storage areas in the seed
Explanation: 

Detailed explanation-1: -The kidney bean seed contains two thick fleshy cotyledons that are foods storage organs. Since two cotyledons are seen in bean seeds, they are dicot seeds.

Detailed explanation-2: -A dicot seed has a tiny embryo inside, but it is tucked in between the two halves of the seed. Each half of the seed is referred to as a cotyledon, hence the name dicotyledon. The cotyledon is filled with food and nutrients for the embryo to develop. An example of a dicot seed is the lima bean.

Detailed explanation-3: -In most dicot seeds, the cotyledons store the food that the seed will use to grow until it gets its first true leaves and begins to make its own food. In many monocot seeds, the food supply for the embryo is stored separately in tissue called the endosperm.

Detailed explanation-4: -The two large parts of the seeds are called “cotyledons”. They supply the food for the young plant when it is growing. The bean seed has two parts. Therefore, it is a dicotyledon or dicot for short.

Detailed explanation-5: -Lima beans are good examples of dicot seeds and corn can be used for monocot seeds. The beans will easily open into two halves.
