C

D
Depends
Explanation: 

Detailed explanation-1: -In monocots, the first cotyledon is called scutellum while the second cotyledon is rudimentary and is called – epiblast. It is a small flap-like outgrowth. It is formed by the remains of second cotyledon which is not truly developed in monocots.

Detailed explanation-2: -In most of these plants, there is still food stored in the seed at the time of germination, and the cotyledon continues to take up nutrients and pass them on to the rest of the seedling until it is able to photosynthesize. Dicots are dicotyledonous – they have 2 cotyledons.

Detailed explanation-3: -Angiosperms with two cotyledons are called dicotyledons or dicots. They produce leaves with a netlike pattern of veins and flower parts in multiples of four or five. Apples, cherries, beans, squashes, and tomatoes are common dicots.

Detailed explanation-4: -As opposed to monocots, dicots (also called eudicots) have two cotyledons during germination which supply the young plant with food and nutrients. The leaves of dicot plants come in a variety of shapes and sizes and the veins form branching patterns.
