Miguel has four family members who plan to come to his graduation on Sunday afternoon, but it is likely that only three of them will be allowed to attend. Normally graduation is held in the football stadium, where there is no limit on the number of family members who can attend. However, the ceremony is relocated to the gymnasium if it rains, and each graduate receives just three admission tickets for use by family members. The conclusion of the argument is most strongly supported if which one of the following is assumed?
A: Miguel has several friends who have fewer than three family members coming to graduation.
B: Miguel's graduating class is much larger than usual.
C: Miguel has a fifth family member who is unable to come to his graduation.
D: The weather service has indicated that there is a very high likelihood of rain on Sunday afternoon.
