Question

an api key can help ______ sensitive data and prevent hackers from putting corporate networks at risk.
network
secure
lock
program

Explanation:

An API key is used for authentication and authorization. Its main purpose is to ensure that only authorized users or applications can access the data. "Secure" means to make something safe from harm or danger. In the context of data, an API key helps in safeguarding (securing) sensitive data. "Network" refers to a group of interconnected computers or systems. "Lock" is a more physical or simplistic way of restricting access (not typically used in the context of API keys for data protection in a corporate network sense). "Program" refers to a set of instructions for a computer. So, the most appropriate word is "secure".

Answer:

secure
