Correct order of energy in the given sub-shells is:

Explanation

Option C is correct.The correct order of energy in the given subshells is 5s>3d>4s>3p.The energy of an electron subshell is determined by two factors: the principal quantum number (n) and the angular momentum quantum number (l). The principal quantum number tells us the energy level of the subshell, and the angular momentum quantum number tells us the shape of the subshell. In general, subshells with higher principal quantum numbers have higher energy than subshells with lower principal quantum numbers. So, 5s has a higher energy than 4s, and 3d has a higher energy than 3p. However, the angular momentum quantum number also plays a role in determining the energy of a subshell. Subshells with the same principal quantum number but different angular momentum quantum numbers have different energies, with subshells with higher angular momentum quantum numbers having higher energy. So, 3d has a higher energy than 3p, even though they have the same principal quantum number.Therefore, the correct order of energy in the given subshells is 5s>3d>4s>3p.
