Right answer is (a) True

Easiest explanation: Dynamic pressure is directly proportional to the flow speed. The formula for dynamic pressure is q=\(\frac{1}{2}\)γPM^2 where q=dynamic pressure, P is pressure of the fluid, M is mach number of that medium and γ is the ratio of specific heat at constant pressure to that of specific heat at constant volume.
