In the early days of life on Earth, plants were exposed to extremely high doses of ultraviolet radiation. Constant UV exposure resulted in some land plants developing narrow leaves with thick, waxy cuticles. Over many, many generations, these narrow leaves evolved into needles.
Relate the development of plant needles to the occurrence of mutations.

A Plant needles adaptations for survival that some plants developed due to high temperatures on Earth.Plant needles adaptations for survival that some plants developed due to high temperatures on Earth.
B Plant needles are the result of leaf cell mutations that made some leaves thick and waxy, while other leaves did not change.Plant needles are the result of leaf cell mutations that made some leaves thick and waxy, while other leaves did not change.
C Plant needles are the result of neutral mutations to leaf tissue that would neither help nor harm the plants living in such a harsh environment.Plant needles are the result of neutral mutations to leaf tissue that would neither help nor harm the plants living in such a harsh environment.
D Plant needles were a beneficial mutation that increased survival of certain plants that reproduced and passed the mutated gene to offspring.
