NEET 2022 Chemistry question on Equilibrium

3O2(g)⇌2O3(g)3\text{O}_2(g) \rightleftharpoons 2\text{O}_3(g)
For the above reaction at 298 K, KCK_C is found to be 3.0×10−593.0 \times 10^{-59}. If the concentration of O2\text{O}_2 at equilibrium is 0.040 M then concentration of O3\text{O}_3 in M is
  1. A.
    4.38×10−324.38 \times 10^{-32}
  2. B.
    1.9×10−631.9 \times 10^{-63}
  3. C.
    2.4×10312.4 \times 10^{31}
