\( \begin{array}{l}\text { When working with arrays, most programming } \\ \text { languages perform } \\ \text { allow programs to use invalid subscripts. } \\ \text { buffer overrun protection } \\ \text { None of these } \\ \text { array bounds checking } \\ \text { bitwise data execution } \\ \text { subscript binding }\end{array} \)

The problem presents a list of options related to array handling in programming languages, specifically focusing on how they manage subscripts. Let's analyze the options provided: 1. **Invalid subscripts**: This refers to accessing an array with an index that is out of its defined range. 2. **Buffer overrun protection**: This is a security measure to prevent writing data outside the bounds of allocated memory. 3. **None of these**: This option suggests that none of the other options are correct. 4. **Array bounds checking**: This is a technique used to ensure that any access to an array is within its defined limits. 5. **Bitwise data execution**: This is not directly related to array subscripting. 6. **Subscript binding**: This term is not commonly used in the context of array handling. From the analysis, the most relevant option that addresses the issue of using invalid subscripts in programming languages is **array bounds checking**. This technique is specifically designed to prevent access to invalid indices, thereby protecting against potential errors and vulnerabilities. Thus, the correct answer is: **Array bounds checking**.
