Final answer:

The correct electron configuration for zinc is option A) 1s² 2s² 2p¶ 3s² 3p¶ 4s² 3d¹⁰.

Step-by-step explanation:

The electron configuration for zinc (Zn) is represented as the: 1s² 2s² 2p¶ 3s² 3p¶ 4s² 3d¹⁰. Thus, the correct option for the electron configuration of zinc is A) 1s² 2s² 2p¶ 3s² 3p¶ 4s² 3d¹⁰. Zinc, as a member of the transition metals (Group 12), has a pseudo noble-gas electron configuration in its ionized form Zn²⁺, which is [Ar]3d¹⁰ after losing the two electrons from its 4s orbital.
