The correct option is D A

Number of boys in A$=0$

Number of boys in B$=\frac{15}{100}\times 1200-\frac{10}{100}\times 800=100$

Number of boys in C$=\frac{5}{100}\times 1200-\frac{2}{100}\times 800=44$

Number of boys in D$=\frac{35}{100}\times 1200-\frac{30}{100}\times 800=180$

Number of boys in E$=32$

Number of boys in F$=156-112=44$
