Correct Answer: Disregard

Solution : The most appropriate choice is the second option.

Contemplate means to carefully consider or think about something deeply. Its antonym, disregard, means to pay no attention to or ignore something.

The meanings of the other options are as follows:

• Ruminate: While similar, "ruminate" shares similarities with "contemplate", as it also means to think deeply or ponder.
• Meditate: This is another word close in meaning to "contemplate," referring to focused and often introspective thinking or reflection.
• Retract: This means to take back or withdraw a statement or action, not directly opposite in meaning to "contemplate."
