Quizplus · Accepted Answer

Emilie is speculating about the duration of their marriage, which is related to their longevity or how long they are expected to live. Therefore, the best choice for this scenario is longevity (choice C). Choice A (average life duration) would refer to the average length of life in a particular population, while choice B (probabilistic age at death) would refer to the probability of an individual reaching a certain age based on different factors. Choice D (useful life expectancies) typically refers to the number of years a person can expect to live in good health, without disability or major illnesses. None of these options are as closely related to the scenario described as choice C (longevity).
