B.

Let PR=h; RS=x;QR=5-x

16= h^2+x^2 from rt triangle PQR
9=h^2+(5-x)^2 from rt triangle PRS

Solve for h from the two equations.

I solved by ratio method.

QS=5 based on the 3-4-5 triangle rule. Notice, the angle of both QPR and PRS is 90 degrees. So, both triangle share the same ratio. PR:RS:PS=3x:4x:5x.

Find common multiplier x frm length of PS,
----> 4=5x
----> x=4/5

Hence, PR= 3*4/5=12/5
