Correct Answer (Detailed Explanation is Below)
B. <cstdlib>
Detailed Explanation
Answer: (B) <cstdlib>
The C++ header <cstdlib> provides access to several functions originating from the C standard library, including dynamic memory functions such as malloc(), calloc(), realloc() and free().
These functions are available in C++ for compatibility with C-style programming, although modern C++ generally provides higher-level memory-management facilities.
<iostream> is primarily used for input and output, while <string> provides the C++ string class and related functionality.
