Final answer:
The appropriate storage for a resizable array of resizable C-style strings is the vector<string> option.
Step-by-step explanation:
The appropriate storage for a resizable array of resizable C-style strings would be the vector<string> option. The vector container in C++ allows for dynamic resizing of the array and the string type represents C-style strings. Therefore, the combination of vector and string provides a suitable solution for this scenario.
