Answer:
B). Instead
Explanation:
As per the question, the most appropriate word to complete the given sentence would be 'instead.' Thus, the complete sentence reads as:
'Instead, the constitution breaks the U.S. Government into three branches.'
It offers a complete and accomplished meaning. It implies that 'in comparison to the present two branches of the federal government, the constitution instead divides the United States Govt. three equal yet independent branches.' The other word fails to go as per the context of the sentence and convey an incomplete thought as they either include a subordinating conjunction('although', 'before') or require contextual background(as 'in conclusion'). Thus, option B is the correct answer.
