JEE Advanced 2023 Physics question on Units and Measurements

Young's modulus of elasticity YY is expressed in terms of three derived quantities, namely, the gravitational constant GG, Planck's constant hh and the speed of light cc, as Y=cαhβGγY = c^\alpha h^\beta G^\gamma. Which of the following is the correct option?
  1. A.
    α=7, β=−1, γ=−2\alpha = 7, \ \beta = -1, \ \gamma = -2
  2. B.
    α=−7, β=−1, γ=−2\alpha = -7, \ \beta = -1, \ \gamma = -2
  3. C.
    α=7, β=−1, γ=2\alpha = 7, \ \beta = -1, \ \gamma = 2
  4. D.
    α=−7, β=1, γ=−2\alpha = -7, \ \beta = 1, \ \gamma = -2
