Options

A. A decrease in the ionisation potential
B. An increase in the ionisation potential
C. No effect on the ionisation potential
D. An increase in the attraction of the nucleus to the electrons

Explanation

Screening effect i.e., repulsion in between the `e^(-)` if its increases then less amount of energy will required to remove an `e^(-)` from outermost shell.
