Thanks to a Novel Recessive Mutation, a Certain Plant Species

Thanks to a novel recessive mutation, a certain plant species has begun to invade colder Arctic regions outside of its normal range. However, this cold-tolerant mutation has not yet become fixed in the population. A second mutation arises that promotes self-pollination. Do you predict that the self-pollination allele will be selected for in the Arctic regions? Why or why not?

A) Yes. The self-pollinated plant is more likely to maintain the cold-tolerant mutation, and plants in the Arctic are unlikely to be visited by pollinators.
B) No. Outcrossing is always beneficial, since it enhances genetic diversity.
C) No. Plants that produce flowers must be cross-pollinated for proper seed development.
D) Cannot make a prediction from the information given.
