Final answer:
The false statement is that an array's length field contains the highest value that can be used as an array's subscript, when it actually represents the total number of elements in the array.
Step-by-step explanation:
The false statement among the options provided is: c. An array's length field contains the highest value that can be used as the array's subscript.
This statement is false because an array's length field contains the total number of elements that the array can hold, which is one more than the highest subscript index (since array indexing starts at 0). The correct statement should be: An array's length field contains the number of elements in the array, which is one more than the highest value that can be used as the array's subscript.
