dear u 9 it's a concept in physics that every symmetry in nature leads to a conservation law. here symmetry in time leads to conservation of energy.
![eduncle-logo-app]()
symmetry in angular velocity leads to conservation of angular momentum. and so on.

according to me, option c is correct. because Hamiltonian is independent of time so energy is conserved . and also z-component of angular momentum is conserved.
