Answer:


\boxed{k=(p)/(r \ s) }

Second option is correct.

Explanation:

We have been given that p varies jointly with r and s.

Thus, we can write it mathematically as


p=krs

Here, k is the constant of variation.

Now, we have to find the value of k.

Divide the above equation by rs


(p)/(r \ s)=(kr\ s)/(rs)


k=(p)/(r s)

Hence, the value of k is
k=(p)/(r s)

Second option is correct.
