Answer:
B) more genetic variation
B) when the organisms produce offspring
Explanation:
More genetic variation means the species is most likely to not die out whenever the environment changes. Take a group of giraffes with varying neck lengths, for example. If the height of the trees were to change, then less of them would die of starvation.
Genes are created through reproduction. During reproduction, an organism with different genes from its parents occurs, creating more genetic variation. Additionally, mutations can also occur, resulting in genes not from either parent.
