Correct Answer: hide

Solution : The correct answer is the second option.

Explanation: In this context, we have to consider words that represent the opposite action or meaning of apprise, which means to inform or notify. Hide is the most appropriate antonym in this scenario, as it denotes keeping information or knowledge concealed, contrasting with the act of apprising or informing.

The meaning of the other options is as follows:

• Notify: This word means to inform someone or give notice.
• Enlighten: This word means to give someone greater knowledge or insight, often in a way that imparts wisdom or understanding.
• Inform: This word means to convey information or provide details.

Therefore, the correct antonym is hide.
