According to the rules of the universitys housing lottery

According to the rules of the university’s housing lottery, the only students guaranteed dormitory rooms are fourth-year students. In addition, any fourth-year student on the dean’s list can choose a dormitory room before anyone who is not a fourth-year student. Which one of the following inferences is most strongly supported by the rules described above?
(A) Benizer is a fourth-year student who is not on the dean’s list, so she is not guaranteed a dormitory room.
(B) Ivan and Naomi are both fourth-year students but only Naomi is on the dean’s list. Therefore, Ivan can choose a dormitory room before Naomi.
(C) Halle, a third-year student, is on the dean’s list. Thus, she is guaranteed a dormitory room.
(D) Gerald and Katrina are both on the dean’s list but only Gerald is a fourth-year student. Thus, Gerald can choose a dormitory room before Katrina.
(E) Anissa is a fourth-year student who is on the dean’s list. Thus, since Jehan is a second-year student who is also on the dean’s list, he can choose a dormitory room before Anissa.
