The sentence that illustrates correct English grammar effectively conveys a clear message about the benefits of washing hands before eating. It uses present tense appropriately with the verb "reduces," which agrees with the singular subject "Washing your hands." Additionally, the phrase "your chance of ingesting extra bacteria" is grammatically sound and correctly uses the term "chance" in a context that indicates a reduction in risk related to health.

In contrast, the other sentences contain grammatical errors that hinder their correctness. For instance, the first choice lacks clarity and completeness and could be simplified by removing "to" for a more concise structure such as "Hiking helps improve respiratory health." The third option has a subject-verb disagreement, as "doesn't" should be followed only by the base form of the verb, making "enjoys" incorrect; it should simply be "doesn't enjoy." Lastly, the fourth choice shows a subject-verb agreement error, where "They was" should use "were" to match the plural subject "They."
