Which of the following is a felony concerning bribery?

Offering a bribe to a peace officer is considered a felony under California Penal Code. This law is designed to uphold the integrity of law enforcement agencies and to prevent corruption within the ranks of those tasked with enforcing the law. A bribe is typically understood as a payment made with the intent to influence the actions of a public servant, such as a peace officer, in their official duties.

In contrast, asking for a discount or offering a better salary, while potentially unethical, do not necessarily fit the legal definition of bribery. These actions can often occur within normal business and employment practices, and do not constitute an attempt to compromise the integrity of public service. Similarly, requesting a favor, depending on the context, may not involve anything that undermines ethical standards or legal statutes, as it might simply represent a personal request unrelated to any public office.

Thus, the only choice that clearly aligns with the criteria for felony bribery is the offering of a bribe to a peace officer.
