Assume friction factor for both the cases of pipe flow is the same

Question

In a fully developed turbulent flow through a circular pipe, a head loss of h₁ is observed. The diameter of the pipe is increased by 10% for the same flow rate and a head loss of h₂ is noted. Assume friction factor for both the cases of pipe flow is the same. The ratio of $\frac{h_{2}}{h_{1}}$  is closest to                                       

      (a) 0.34                                                               (b) 0.62

      (c) 0.87                                                               (d) 1.00
