The table shows that 14 out of 30 boys prefer math and that 16 out of 32 girls prefer math
A. The relationship is proportional because 16-4=2 and 32-30=2
B. The relationship is proportional because 30-14 = 16 and 32-16 = 16
C. The relationship is not proportional because 14/16=7/8 and 30/32=15/16
D. Relationship is not proportional because 14/30= 17/15 and 16/32=1/2
