The true statement is (d) the product of c and b could be multiplied by one-third.
<h3>How to determine the true statement?</h3>
The variation equation can be represented as:
When the value of d is tripled, the equation becomes
This means that: the product of c and b could be multiplied by one-third.
Hence, the true statement is (d)
