Correct Answer: Eventual

Solution : The correct choice is the fourth option.

Explanation:

Ulterior refers to something beyond what is evident or currently visible, often implying hidden motives or intentions. Eventual means something that will happen in the future, suggesting a final outcome or result that may not be immediately apparent. Both of the words convey a sense of something occurring or existing beyond the current situation or timeframe.

The meanings of the other options are as follows:

• Anterior: It means before in time or place.
• Prior: It means before in time or order.
• Ancient: It refers to something that is very old.
