Answer:
B.) It contains two or more simple sentences.
D.) It includes conjunctions such as <em>for, and, nor, but, or, yet, </em>and <em>so.</em>
Explanation:
A compound sentence contains at least <em>two independent clauses</em> separated by a comma and linked by a coordinating conjunction.
An <em>independent clause</em> is a clause that has a subject, a verb and can stand alone as a sentence. (answer choice B)
Coordinating conjunctions are <em>for, and, nor, but, or, yet, </em>and <em>so. </em>(answer choice D)
THEY look much better than the others - would be appropriate if you were referring to both a person and an object.
THOSE look much better than the others - would be appropriate if you were referring to an item not a person.
I am not sure but hope this helped.
