Final answer:
Benji and Annie are the individuals from the scenarios provided who meet the IRS age test for a qualifying child. Benji is a full-time student under 24, and Annie is any age but permanently and totally disabled.
Step-by-step explanation:
To determine which taxpayer has a potential qualifying child that meets the age test for tax purposes, we need to reference the Internal Revenue Service (IRS) guidelines. According to the IRS, a qualifying child must be:
- Under the age of 19 at the end of the year and younger than the taxpayer (or the taxpayer's spouse if filing jointly),
- Under the age of 24 at the end of the year, a full-time student, and younger than the taxpayer (or the taxpayer's spouse if filing jointly),
- Any age if permanently and totally disabled.
Based on the scenarios provided:
- Aiyden and Zuri's son, Caleb, at 25 years old, is beyond the age threshold, even though he is a full-time student.
- Lexi's daughter, Josie, at 19 years old and not a student or disabled, also does not meet the age test.
- Omana's brother, Benji, is a 23-year-old full-time student, which makes him qualify under the age test.
- Rohan's sister, Annie, at 25 years old and totally disabled, meets the criteria based on the disability exception.
Therefore, Benji and Annie are the individuals who meet the age test for a qualifying child under the given scenarios.
