Broken by andrew johnson in 1868, the tenure of office act of 1867 a) forbid presidents from campaigning for candidates in any congressional elections c) forbid presidents from removing senators and representatives who did not support his domestic or foreign strategies d) prohibited the president from removing officials who had been appointed with the consent of the senate without first obtaining senatorial approval.

The correct answer is
d) prohibited the President from removing officials who had been appointed with the consent of the Senate without first obtaining senatorial approval.

The act denied the president the right to remove officials that were appointed in conjunction with the senate, without having Senate's approval. If a president did that then it would be considered illegal and there could even be an impeachment if the senate wanted.
