Answer : A

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:

• 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
• after : It is used to express that one event follows another
• 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

Here in the question, we understand that the speaker is expressing to stop at a petrol pump prior to running out of petrol.

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

Thus, the correct complete sentence is:

Stop at a petrol pump BEFORE we run out of the petrol.
