Answer:
A
Explanation:
Proportional is where everything will match
so we have 2x3=6 5x3=15 8x3=24 11x3=33
This works because it continues the same line of multiplication (x3).
But like B, you start with 4,4=16 which works, but now you have 5x4=21, which will not work because 5x4 will never equal 21
Your answer is A
