the electron configuration of an element in its ground state is illustrated above. which, if any, of the three principles that determine the most stable electron configuration of an element does this configuration disobey

hello your question is incomplete attached below is missing part

answer : Pauli's exclusion principle

Explanation:

The principle that was disobeyed is Pauli's exclusion principle this is because the  Pauli's exclusion principle states that no two electrons can have the same set of quantum number.

In Box A the two electrons , have the same spin which means  they have the same quantum number ( disobeys Pauli's exclusion principle )
