Which of the following properties is affected by stable configuration ...
The addition of extra electron is difficult to the atom having stable configuration and so electron affinity will be less or zero. Similarly the removal of electron is quite difficult for stable configuration and so ionisation energy is higher. Hence electron affinity and ionisation energy both are affected by stable configuration.

Stable Configuration and Its Effects on Properties of an Atom
Stable configuration refers to the arrangement of electrons in the outermost shell of an atom, which determines its chemical and physical properties. The following properties are affected by the stable configuration of an atom:
Electronegativity
Electronegativity is the ability of an atom to attract electrons towards itself in a covalent bond. If an atom has a stable configuration, it means that its outermost shell is full, and it does not require any more electrons to complete it. Therefore, such an atom will have a low electronegativity since it does not need to attract electrons towards itself.
Ionisation Potential
Ionisation potential is the energy required to remove an electron from an atom. If an atom has a stable configuration, it means that its outermost shell is full, and it is difficult to remove an electron from it. Therefore, such an atom will have a high ionisation potential since it requires more energy to remove an electron.
Electron Affinity
Electron affinity is the energy released when an atom gains an electron to form an anion. If an atom has a stable configuration, it means that its outermost shell is full, and it does not require any more electrons to complete it. Therefore, such an atom will have a low electron affinity since it does not have a strong tendency to gain electrons.
Conclusion
In summary, the stable configuration of an atom affects its electronegativity, ionisation potential, and electron affinity. An atom with a full outermost shell will have low electronegativity and electron affinity but high ionisation potential.
