The correct option is C before

Answer : C

Subordinating Conjugation : 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 in relation to time:

• when : It is used to refer to a particular time; at or during the time that; also it is used to show that one event happens slightly after another
  
• if : It is not used to show a relationship of time but is used to introduce a conditional clause
• before : It is used to express that one event precedes another
  
• until : It is used to express the time when an event or action comes to an end

Here in the question, we understand that the speaker is expressing that he "will" have a bath and then go to bed. Thus the sentence is showing a time relation between both the events, where one event is occurring prior to the other.

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

Thus, the correct complete sentence is:

I will have a bath BEFORE I go to bed.
