Water Flowing Through a Cylindrical Pipe Suddenly Comes to a Section

Water flowing through a cylindrical pipe suddenly comes to a section of pipe where the diameter decreases to 86% of its previous value.If the speed of the water in the larger section of the pipe was $32 \mathrm {~m} / \mathrm { s }$ what is its speed in this smaller section if the water behaves like an ideal incompressible fluid?

A) 43 m/s
B) 37 m/s
C) 28 m/s
D) 24 m/s
