[lightheart]

Sample test:
The accident was ____ his careless use of gun.
A. because of
B. owing to
C. due to
D, on account of

given answer: C

Question:
I chose C here but still don’t have a clear idea of their distinctions, especially between “owing to” and “due to”. Could you please explain why it’s better to use “due to” here?

Thanks if you would help : )

Due to is used as a way of rephrasing owing to. All of these options are used depending on the tense of the verb located at the start.
