Correct Answer: Disregard

Solution : The correct choice is the second option .

The word care implies a sense of concern, attention, or consideration for something or someone. Its opposite would be a lack of concern or attention. Disregard is the correct antonym in this context. It means to pay no attention to or ignore, which is opposite to the idea of caring.

The meanings of the other options are as follows:

• Concern : It means consideration for something or someone.
• Worry : It means anxiety or concern about something.
• Attention : It means focusing on or giving consideration to something.
