Answer:
D. Members of Congress could issue statements opposing the appointment but have no formal power to block it.
Step-by-step explanation:
The inability of Congress to block the election of house members exist to limit the power of congress as an effort to maintain the balance of power within the government . In the election of house members, the Senates are the one that have the power to block the appointment, not the congress.
If the congress managed to convince the senate to block it, the senates will have to vote the final decisions among their own members,. The appointment will be cancelled if they got more than 2/3 votes.
