The dimensions of the area A of a black hole can be written in terms of the universal gravitational constant G, its mass M and the speed of light c as `A=G^(alpha)M^(beta)c^(gamma)`. Here -
A. `alpha=-2, beta=-2`, and `gamma=4`
B. `alpha=2, beta=2` and `gamma=-4`
C. `alpha=3, beta=3`, and `gamma=-2`
D. `alpha=-3, beta=-3` and `gamma=2`
