What does "salubrious" refer to in health terminology?

The term "salubrious" refers to something that is beneficial to health or promotes healthiness. It is often used in contexts such as describing environments that are conducive to well-being or conditions that have a positive impact on one's physical or mental health. When something is characterized as salubrious, it implies a quality that supports or enhances overall health and vitality, which aligns perfectly with the choice indicating having health benefits.

Other options, while they might sound plausible or have their own contexts, do not relate to the core health-focused definition of salubrious. A type of sweetener does not pertain to health benefits in the same sense, and revival from apparent death or infestation with bacteria are more clinical or negative conditions rather than something that promotes health. Thus, the choice highlighting health benefits is the one that accurately captures the essence of the term.
