Answer:
Double fertilization
Explanation:
The phenomenon of double fertilization is unique to flowering plants (i.e., angiosperms). Each pollen grain produces two male gametes (sperm cells), one of which fertilizes the egg to form the zygote, whereas the other sperm fuses with polar nuclei in the female gametophyte in order to form a triploid cell (3n) called endosperm. Subsequently, this endosperm will support embryonic growth by supplying storage nutrients and by serving as a mechanical barrier during seed development and germination.
Salts usually. It depends on the base used. For example, if it is a carbonate reacting with acid, you get carbon dioxide, a carbonate salt and water.

Carbon emissions are lowering and waters are clearing
If it were single celled, then it would need some form of protection so the answer would be C. an outer covering
