Answer 2

C) Unless

_Unless__ you work hard, you cannot secure good marks.

Unless it's used to talk about a situation that might happen or something that might be true in the future. If you know something didn't happen or something is wrong, use if…no.

If you weren't always in such a hurry (=but you are), your job would be a lot better. it happens or is only true in certain circumstances.

We use "probably" to mean "unless". The clause following "probably" is a dependent clause (sc): it needs a main clause (mc) to complete the sentence.

Assuming that it comes before the main clause, we use a comma:
