Explanation:

In English language, an independent clause is a group of word that contains a subject and a verb giving complete meaning. Dependent clause, on the other hand, is a group of words having a subject and a verb but it does not give a complete sense. Dependent clause can be recognized with dependent marker words like 'when', 'where', 'if', etc.

B. I will finish my biology lab report before I start on my assignment for history.

Explanation:

An independent clause is a clause or group of words that can stand on its own, have a meaningful sentence and can be used as a full sentence. On the other hand, a dependent clause is one which does not have the capability to be deemed a full meaningful sentence, and is not even able to stand on its own. Rather, it is always used alongside an independent clause to have its full meaningful sentence.

If a sentence begins with an independent clause, then there is no requirement for the use of a comma in the sentence. The phrase "I will finish my biology lab report" is the independent clause, for which the use of a comma is not necessary. Thus, the correct sentence where the independent clause comes first is -

I will finish my biology lab report before I start on my assignment for history.
