there are 6 questions, half of six is 3
So we're looking for how many students got more than 3 correct
in the 4 column there are 3, in the 5th column 4, and in the 6th column there are also 4
So now we have to add up how many got more than half together
3+4+4=11
11 students got more than half correct, so your answer is B
