Yes, you’re right, I choose B ^^
But what’s the difference between “current” and “present” as they both have the meaning of “happening or existing now” (in Longman dictionary) ?
That’s why I would say that both could be considered right. (B) is the common expression though. It has the edge over (A) only because it is more prevalent.
I see you have posted another question in a different thread where there is also more han one possible correct answer. I think it’s a poor test.
