B :
Every boy and every girl in this section are good player.
C :
Each girl and every boy in this section are good player.
D :
Each boy and each girl in this section are good player.
Answer: B Options A,C and D are erroneous because the adverbs strangely and often don't go together. Further, mathematics is taken as a singular subject and is therefore followed by a singular verb.
