b. enclosed in the stigma of a flower
c. within an ovule contained within an ovary of a flower
d. packed into pollen sacs within the anthers found on a stamen

Explanation:

Angiosperm is known as flowering plants and bears their seeds within a fruit. They are vascular plants they have stem, leaves, and roots. They represent approximately 80% of all living green plants. They are the most abundant and diverse plants throughout the globe.

Angiosperms are vascular seed plants where the ovule or egg is fertilized and develops into the seed in an enclosed hollow ovary. The ovary is also enclosed in a flower, it is the part of the plant angiospermous plant which contains both male or female reproductive organs. Fruits are derived from the maturing flower organs present in the angiosperm plants.

They are also defined as vascular plants with fruit, seeds, and flowers for reproduction.  

the diploid number of chromosomes is sometimes represented by the symbol 2n. for the fruit fly, the diploid number is 8, which can be written as 2n = 8, where n represents twice the number of chromosomes in a sperm or egg cell.

if the type of the food available changes, then the frequency of beak types will change, because birds with beaks more suited to the available food will be more successful over time.
