Correct Answer: Disobliging

Solution : The most appropriate choice is the third option.

"Accommodating" means to be willing to adapt to or please others' needs and preferences, often at the expense of one's own interests.

The antonym "disobliging" means unwilling to accommodate or help others, being uncooperative, and not accommodating.

The meanings of the other options are as follows:

• "Reconciling" means bringing together or resolving differences, which is not the opposite of accommodating.
• "Strenuous" means requiring a lot of effort and energy, which is not related to the concept of being accommodating.
• "Gratifying" means pleasing or satisfying, which is not the opposite of accommodating.
