Answer: An observational study where lifespan is the explanatory variable.
Explanation:
The correct option will be fomites.
<h3>What are fomites?</h3>
Fomites are non-living materials that are capable of carrying the infective structures of pathogenic organisms to a healthy person.
Infective structures of pathogens are spores or any other materials that are capable of making humans sick either directly or indirectly.
Fomites could be in the form of door handles in houses or offices, handrails, articles of clothing, cooking utensils, and so on.
Fomites and vectors function the same way. However, vectors are living organisms, unlike fomites. Both act as drivers that move pathogens or their propagules to humans.
