the house may refuse to seat a member-elect only if he or she

a. has engaged in disorderly behavior
b. does not meet constitutional standards of age, citizenship, and residency
c. does not meet informal standards set by two-thirds of the members

b.

Yes, the answer is (b) because of a 1969 Supreme Court decision. Before that, the House could reject any elected member for failure to meet arbitrary standards, which usually amounted to being convicted of a crime during or immediately prior to a term of office.

To determine the answer, we need to understand the requirements for a member-elect to be seated in a house.

The requirements for a member-elect to be seated in a house typically include constitutional standards of age, citizenship, and residency. These standards are set by the Constitution and serve as basic eligibility criteria for individuals to hold office.

Therefore, the correct answer is option b: "does not meet constitutional standards of age, citizenship, and residency".

To conclude this answer, we can say that the house may refuse to seat a member-elect if they fail to meet the constitutional standards of age, citizenship, and residency.
