What is the meaning of the term stultify?

The term "stultify" refers to causing someone or something to become dull, ineffective, or less enthusiastic, particularly by preventing growth or development. In this context, it relates to diminishing a person's energy or motivation, leading to a state where they may feel unproductive or apathetic. This aligns with the answer choice that highlights the loss of enthusiasm and initiative, as stultification effectively negates the desire or ability to engage actively in tasks.

The other options suggest positive outcomes such as stimulating creativity, encouraging participation, or enhancing learning experiences, which do not align with the definition of stultify. Rather than fostering energy or engagement, stultification leads to stagnation or a decline in motivation, making the correct choice clear.
