Some members of the United States Congress opposed the annecation of Texas mainly because "c- They did not want to take control of Texas from Mexico".
D.) they did not want to support US president Sam Houston
the answer is B
The correct answer is B: They did not want to anger Mexico by going against a treaty. Many congressmen feared that annexing Texas would lead to war with Mexico, since it did not recognize the sovereignty of what it considered a rebellious province. It was therefore unlikely that Mexico would allow the United States to annex Texas without an armed struggle.
