OS imposes per process limits on the number of open file descriptors.

Answer: Option A

This question is asking about the limits on how many files a program can have open at the same time.

Think of a file descriptor like a little key that lets a program access a file.

Operating Systems (OS) are like the managers of your computer. They have rules to keep things running smoothly. One of these rules is that each program can only have a certain number of file descriptors (keys) at the same time.

So, the answer is True.
