Answer 2

A complete sentence should not traditionally begin with a coordinating conjunction like 'for'. Modern usage does allow more flexibility, but D) For is the correct option for standard academic writing conventions.

Step-by-step explanation:

A complete sentence traditionally should not begin with a coordinating conjunction, such as and, but, or, or for; however, in modern English usage, this rule has become more flexible with stylistic choices permitting such structures for rhetorical effect or conversational tone.

In the context of standard academic writing and as per the traditional rules of grammar set forth in education, the most acceptable answer is D) For, as sentences typically do not begin with the word for when it is being used as a coordinating conjunction.

According to the rules pertaining to compound sentences and run-on sentences, it is advised to use coordinating conjunctions to join two independent clauses with a comma preceding the conjunction (e.g., The company is expanding, and new positions are being created.). It is essential to ensure that independent clauses are connected properly in order to avoid run-on sentences and maintain the clarity of writing.
