Among all the sentences in the choices, this sentence best
illustrates a pair of sentence that are joined by an understood relationship.
If we analyze the sentences, the first sentence states that Smiley is a
detective who just scanned the dim hallway. Dim hallways usually mean that
there might be danger ahead therefore in the second sentence; the detective
took out his gun from its holster.

It is not written specifically but the sentences have this connotation.

Answer : Option C) Detective Smiley scanned the dim hallway. He pulled his pistol from its holster.

Explanation : Amongst the given other choices there seems to be no relationship between two consecutive sentences. The only sentence which seemed to have a connection between previous and later sentence was option C. Where it is clearly stated that the detective named as Smiley was walking through the hallway which was dimly lit. The second sentence has a co-relation to the previous one as it extends the sentence. Detective smiley then pulled out his pistol from his holster after walking through the hallway.

This confirms that the correct answer for this question is Option C.
