Answer
Option B is correct.
(12/5) = 2.4
Step-by-step explanation
If a varies directly as b, which can be written as
a ∝ b
Introducing the constant of variation, k, we have
a ∝ b
a = kb
Looking at the options, we can see that the last three options are the only ones in this form and of the three of them, only option B has the value before b equal to 2.4
