We can create the equation:

(p + 4p)/2 = 10

5p = 20

p = 4

Theory

    ➡ Average = Sum of all the Values / Total Number of Values

The average of \(p\) and \(4p\) is 10

Average = \(\frac{Sum}{2}\) = \(\frac{p + 4p }{2}\) = \(\frac{5p}{2}\) = 10 (given)
=> 5p = 10*2 = 20
=> p = \(\frac{20}{5}\) = 4

So, Answer will be C.
Hope it helps!
