In a hydrogen atom, which orbital is higher in energy than a 3s-orbital?

Which of the following statements in relation to the hydrogen atom is correct? 3s orbital is lower in energy than 3p orbital, 3p orbital is lower in energy than 3d orbital, 3s and 3p orbitals are lower in energy than 3d orbital, 3s and 3p orbital all have the same energy

4s orbitals has less energy than 3d orbital

4s orbitals has less energy than 3d orbital

4s orbitals has less energy than 3d orbital

If the energy of a hydrogen atom in nth orbit is E_(n) , then energy in the nth orbit of a singly ionised helium atom will be
