Correct Answer:
B. To fully accept something, especially a trick or lie
The idiom "Swallow the bait" means to fully accept something, especially a trick or lie. This phrase originates from fishing, where a fish takes the bait and gets caught, implying that someone has been deceived or fallen for a trick. It suggests a lack of critical thinking or being easily fooled.
- To ignore a warning is incorrect as swallowing the bait implies falling for something, not disregarding a caution.
- To resist temptation is the opposite; it means succumbing to temptation.
- To speak without thinking is unrelated to the core meaning of being tricked or deceived.
