A
Pollen from the flower being taken from the stamen to the pistil
B
A stem and a seed begin to come through the soil
C
The seeds of the fruit being taken away by birds and dropped in a new location
D

Explanation: 

Detailed explanation-1: -Viviparous germination is one in which a seed germinates inside the fruit while it is still attached to the parent plant. This type of germination is seen in species of Rhizophora (mangroves).

Detailed explanation-2: -Seeds require water to germinate, thus they must drink it. There must be enough moisture for this to happen. Warmer weather may result in more evaporation and less moisture, which would be detrimental to germination. Up to a degree, warmer temperatures promote germination.

Detailed explanation-3: -Few seeds can be soaked overnight in water and the next day, water can be drained from the soaked seeds. Place the soaked seeds on tissue paper, cover them with a wet tissue paper and keep at a warm place. Small growth from the seeds can be seen after a day, it indicates the process of germination.

Detailed explanation-4: -During the early stages of germination, the seedling uses the food stored inside the seeds for its growth. When the seed receives adequate light, water, air, and warmth, it becomes soft and spongy. The seed coat then breaks and the young plant comes out. The young plant develops roots and shoots.
