Answer:
B
Explanation:
Article IV, Sec 3 states that a New Mexico senator "shall not be less than twenty-five years of age" which immediately clears out half the answers and leaves us with two possible answers, those being B and D since they are the only ones who meet the age requirement.
It also states "If any senator or representative permanently removes his residence from... the district from which he was elected, then he shall be deemed to have resigned...", this means that now we know with certainty that it can't be person D, since they recently changed their residence.
