Final answer:
The correct inequality representing the age requirement for a U.S. Presidential candidate is C. P ≥ 35, as the Constitution states a person must be at least 35 years old.
Step-by-step explanation:
The inequality that correctly represents the requirement for a person’s age to run for President of the USA is C. P ≥ 35. According to the United States Constitution, Article II, Section 1, Clause 5, no person is eligible for the office of President unless they have attained the age of thirty-five years. Therefore, the person must be at least 35 years old, which is expressed mathematically as an age P, such that P is greater than or equal to 35.
