The correct answer is

B) After a lot of effort, I finally start the car engine.

To refer to specific past abilities, we use:
- manage to
- be able to
- succeed in + ing

not "could".

Both sentences are correct. In the first one, it is not necessary to go to the lecture, whereas in the second one, it is prohibited to go to the lecture because it is only for first-year students.

Both are correct
- Since the first sentence expresses ~~makes us~~ to ~~understand~~ that ``he`` already took this visa wherever he is, and for how ~~much time~~ ~~does~~ long it works.
- The second sentence explains a coinditional, maybe someone is explaining how that visa works.

a is correct, whereas b is incorrect. We do not use could not to refer to a future possibility.
