The wavelength associated with a moving particle depends upon the power p of its mass m, qth power of its velocity v, and rth power of Planck's constant h. Then the correct set of values of p, q and r is:

• A. p = 1, q = -1, r = -1
• B. p = 1, q = 1, r = 1
• C. p = -1, q = -1, r = -1
• D. p = -1, q = -1, r = 1
