Final answer:
The correct word to complete the sentence is implored.
Step-by-step explanation:
The correct word to complete the sentence is implored. When someone implores, they are asking or begging earnestly for something. In this context, the wife of the victim is asking the court for a harsher punishment against the alleged criminal. The other options - entreated, beseeched, and accosted - do not fit the meaning of asking or begging earnestly.
