___________ my car broke down, I came home late yesterday.

In the above sentence, we see 2 sides of the sentence describing cause and effect – broke down – came home late.

Thus, only option A is suitable.

We see that the answer C – For is also used with the reason clause but not at the beginning of the sentence. Option B – While is not suitable in meaning, and option D – with will combine with a noun, not before a clause because with is a preposition.

Translated. Because my car broke down, I came home late yesterday.
