The correct answer is flowers

What is the key adaptation of angiosperms?

Angiosperms first appeared around 125-100 million years ago, during the late Cretaceous Period.

Flowers and fruit were evolved by angiosperms to attract pollinators and protect their seeds, respectively.

Flowers come in a variety of colours, sizes, and scents, all of which are designed to attract pollinators.

Once fertilised, the egg develops into a seed that is protected by a fleshy fruit.

Many contemporary groups of insects developed when angiosperms evolved in the Cretaceous epoch, including pollinating insects that spurred angiosperm evolution; in many cases, flowers and their pollinators coevolved.

Angiosperms did not originate from gymnosperms, but rather evolved alongside them; nonetheless, it is unknown what sort of plant gave rise to angiosperms.
