If

Answer : B

Subordinating Conjunction : It is a word or phrase used to link a dependent clause to an independent clause.

It is used to:

• show a cause-and-effect relationship between the dependent & subordinate (independent clause)
• to show a relationship involving a transition of time or place between two clause

Let's take a look at the usage of the subordinating conjugations in the options:

• unless : It is used to express a condition under which something will not happen
  
• if : It is used to express a condition that is necessary for something to happen
  
• as soon as : It is used to express that one event happens first and another happens immediately after
• while : It is used to express an action in progress; sometimes this action is interrupted

Here in the question, we understand that the speaker is telling the other person to make him/her a cup of coffee in case the other person happens to wake you earlier than the speaker.

Therefore from among the options, 'If' is the most suitable subordinating conjugation to complete the sentence.

Thus, the correct complete sentence is:

IF you are the first person up in the morning, make me a cup of coffee.
