A species that has experienced a severe bottleneck event would be expected to _______.

A severe bottleneck sharply reduces a population’s size, often removing many genetic variants by chance. With less genetic diversity, the population is less likely to include individuals resistant to a new disease or able to withstand environmental changes, making it more susceptible to disease and famine. Thus, “be more susceptible to disease and famine” is correct; bottlenecks generally reduce, rather than preserve, genetic diversity.
