Chemistry · Structure of atom

Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R).\n Assertion (A): The energies of the orbitals in the same subshell decrease with increase in atomic number (\( Z_{eff} \)).\n Reason (R): Higher atomic number increases the attractive force on electrons, lowering their orbital energy. \nIn the light of the above statements, choose the correct answer from the options given below:

1. Both (A) and (R) are true and (R) is the correct explanation of (A).
2. Both (A) and (R) are true but (R) is NOT the correct explanation of (A).
3. (A) is true but (R) is false.
4. (A) is false but (R) is true.
