Good find. definitely says A is the Answer. Which makes sense, as it B was the answer, then would have to ask “that the hell is is hybrid attack?”
This is definitely a Hybrid attack. Read the following article and it will make perfect sense.

B is correct.
Brute force: Uses different kind of possible key combination. A large number of key combinations are possible. Easy to crack when the length is small. And lot difficult when length is large.
Dictionary: Uses list of known password. Limited numbers of common keys . Easy to crack when the password is common.
Fundamentally, all dictionary attacks are brute force. One difference is that dictionary is sort of a “smart” attack, such that it doesn’t try words that aren’t in the dictionary. BUT you still have to run through “password1”, “password2”, “password3”, etc.
