61. If a population of plants experiences a sudden change in climate, leading to colder temperatures. According to natural selection, which scenario is most likely to lead to adaptation?

Individual plants will shiver and adapt to the cold, passing this adaptation to their offspring.
All plants will eventually develop frost resistance.
Plants with pre-existing genetic variations for cold tolerance will survive and reproduce more, increasing cold-tolerant offspring.
The colder temperature will cause plants to mutate into cold-resistant forms.
