Joshua trees cannot germinate and grow as easily in today's warmer climate. Which of these actions would be most likely to help the species survive climate change?
Limiting the height of the tree.
Becoming a mature plant without leaves.
Growing in a range farther north.
Limiting growth to winter.

I think it is either b or c.

The correct option is C and D.

Explanation:

There are certain plants which require certain temperature ranges to grow such as the Joshua trees. As these plants are not able to grow in warm conditions, hence it is better that these trees be grown in the north where the climate is cooler and best suitable for these Joshua trees. Hence, the correct option is C.

Also, if we want the trees to grow, we can limit their growth to only winters.
