Which of the following individuals is a minor in the FNS household described?

In the context of the Food and Nutrition Services (FNS) framework, a minor is typically defined as an individual who is under the age of 18. In this case, the correct choice identifies Javier as the minor within the household described. This determination is rooted in the eligibility criteria set forth by FNS, which often focuses on the ages of household members when assessing eligibility for various programs and benefits.

When determining which individual is classified as a minor, it's important to consider their ages relative to this definition. Marisela, Maria, and Mario may be of an age that qualifies them as adults, therefore not meeting the criteria to be considered a minor. The specific reasoning hinges on Javier’s age being less than 18, making him the only individual in the household fitting the definition of a minor and, consequently, integral in assessing the household's eligibility for assistance in programs like FNS.
