Which of the following occurs in angiosperms but not in gymnosperms?
A. double fertilization
Both have pollen. Megaspores and swimming sperm don't occur in either.  

If a plant's flowers are very colorful and produce nectar, the plant is probably pollinated by
C. insects
Could also be birds but it wasn't a choice.  Flowers meant for birds tend to be red which isn't seen well by most insects.

Actually double fertilization does occur in some gymnosperms, specifically in genera Gnetum, although it doesn't result in the formation of endosperm.
