Answer:
A) the sexually reproducing species
Explanation:
Although we do not know how the change in temperature directly affects the bacteria species, we can say that the species that reproduces sexually are more likely to thrive because these species are also able to reproduce asexually. In other words, this species handle two mechanisms of reproduction
Unlike the species able to reproduce sexually (and asexually), the other species only reproduces asexually. Therefore, if the change in temperature affects asexual reproduction, the species that have both mechanisms will thrive using sexual reproduction, but the other species (not able to reproduce sexually) will not survive.
