Answer 1

The correct option is A When

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:

• 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
• after : It is used to express that one event follows another
• 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 to ask for help at the time of having any problem. Thus having a problem is immediately followed in time by asking for help.

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

Thus, the correct complete sentence is:

WHEN you have any problem, just ask for help.
