Option B.

Step-by-step explanation:

It is given that two quantities, x and y, are directly proportional. It means

$y\propto x$

y=kx

where, k is constant of proportionality.

We need to find the effect on y if x is tripled.

Let x_1=3x , then

y_1=k(3x)

y_1=3(kx)

y_1=3y

It means y is also tripled.

Therefore, the correct option is B.
