i think its B.
given jap student >=100.
and student studying both =4% of french students.
stat 1 ) we get to know students studying french= 400., but not the total jap students
stat 2) 10% of jap students study french. 
so min no. of jap students = 10% *200=20.
so 20=4% of french students=> french students = min 500(when jap students are 100). so french students are more than japanese.
