A strawberry farmer finds that, after a hard freeze, some of his strawberries are still alive. Which best explains why these strawberries were able to survive?

• They have larger leaves to protect the fruit than the other strawberries.

• They have different genetic variations that cause them to be more resistant to cold temperatures.

• They are able to reproduce more quickly than the other strawberries.

• The color of the strawberries is darker, and they maintain their temperature better than other strawberries.
