A massive black hole of mass m and radius R is spinning with angular velocity `omega`. The power P radiated by it as gravitational waves is given by `P = Gc^(–5)m^(x)R^(y)omega^(z)`, where c and G are speed of light in free space, and the universal gravitational constant , respectively. Then
A. x =` –1`, y = 2, z = 4
B. x = 1, y = 1, z = 4
C. x = `–1`, y = 4, z = 4
D. x = 2, y = 4, z = 6
