Pointer usage can complicate program maintenance primarily because they can obscure the program's data flow. When pointers are utilized extensively, the relationship between the data and the variables that contain it becomes less direct. This can make it challenging for developers to follow how data is modified, tracked, or passed through various functions.

For instance, when pointers reference different memory locations or when multiple pointers refer to the same data, it can become unclear which part of the program is responsible for changes to that data. This leads to a situation where understanding the overall behavior of the program requires more cognitive effort and can introduce bugs that are difficult to trace.

Following the data flow relies heavily on knowing where and how data is stored and manipulated. With pointers, particularly in more complex systems, the clarity of this flow is diminished. This obscured visibility might require more documentation and effort in debugging, increasing the maintenance burden on developers.

The other choices suggest benefits that don’t directly relate to the complexities introduced by pointers. For example, pointers do not inherently improve readability; rather, they can make understanding the code more challenging. Similarly, while pointers can reduce memory usage in certain contexts, that advantage may not outweigh the complications in maintenance. Lastly, while pointers can enhance performance by allowing
