Choose the English sentence that is best captured by this formal sentence:

a. It is necessary for me to pass the course that I pass the exxam, but it is also sufficient for me not to pass the course that I don’t pass the exxam.

b. It is a necessary condition for me to pass the course that I pass the exxam, but it is not sufficient for me to pass the course that I pass the exxam.

c. It is a necessary condition for me to pass the course that I pass the exxam, but it is sufficient that I don’t pass the exxam for me to not pass the course.

d. it is sufficient for me to pass the course that I pass the exxam, but it is not necessary for me to pass the course that I pass the exxam.

I believe A is the right answer but reading these sentences over and over got me so confused right now

Explanation / Answer

I think B is right because passing the course to pass the exam can be necessary condition but this condition may not be the only condition required and there can be other situations as well. Thus, we can say that this condition is necessary but not sufficient.
