Final answer:
The changing climate encouraged domestication by providing longer growing seasons and allowing people to settle in one area and engage in agriculture. Hence, C) is correct.
Step-by-step explanation:
The changing climate encouraged domestication by providing longer growing seasons. As the climate became warmer, people were able to grow more crops for a longer period of time, which encouraged them to settle in one area and engage in agriculture.
This shift from a nomadic hunter-gatherer lifestyle to a settled agricultural lifestyle allowed for the development of permanent settlements and the domestication of plants and animals.
