Answer 1

To choose the pairs which shows a direct proportion:

As we know,

Two quantities are said to be directly proportional if their ratio is constant.

Consider option B, we have

`\begin{gathered} \text{First quantity: }(4)/(3) \\ Simplified\text{ }Second\text{ quantity:}(4)/(3) \end{gathered}`

Since the ratio is constant.

Hence, the correct answer is B.
