Which of these molecular electron configurations describe an excited state?

See attachment with this answer

Explanation:

Electronic configuration:

Definition:

The electronic configuration is defined as the arrangement of electrons in atomic or molecular orbitals.

Electronic configuration is used for:

The electronic configuration describes the ground state of the orbitals present in an atom or also to describe the ionized state of an atom.

Three principles of electronic configuration:

The electronic configuration is based on three principles Hund's Rule, Aufbau's Principle, and Pauli-exclusion principle.

Excited-state of Atom:

The excited state in an atom is the state in which electron revolving around orbitals have a higher energy state than the ground state.
