To answer this question, you need to understand what TSO (Time Sharing Option) is.
TSO (Time Sharing Option) is a feature of the IBM mainframe operating system called z/OS. It allows multiple users to access and use the mainframe system simultaneously. Each user is given a time slice or a portion of the CPU's processing time to execute their tasks.
Based on this information, we can conclude that the statement "TSO - Time Sharing Option" is true. TSO is indeed a time-sharing option that allows multiple users to share and access the resources of the mainframe system concurrently.
Therefore, the correct answer is A) True.
