Final answer:
The pseudo-noble-gas electron configuration is represented by option (c) 1s²2s²2p⁶3s²3d¹⁰4s².
Step-by-step explanation:
The pseudo-noble-gas electron configuration is represented by option (c) 1s²2s²2p⁶3s²3d¹⁰4s². This configuration is similar to the electron configuration of the noble gas krypton (Kr), which is [Kr] 5s²4d¹⁰. The pseudo-noble-gas configuration is achieved by filling the electron orbitals up to the same level as the nearest noble gas.
