The dynamic memory allocation/linking of a program is done during execution. So, the correct answer is b. execution.

Here's a step-by-step explanation:

1. Loading: This is the process of putting the program into memory, which is a prerequisite for execution. However, dynamic memory allocation does not occur at this stage.

2. Execution: This is when the program is running. During execution, the program may request additional memory for its operations. This is when dynamic memory allocation occurs. The program can request memory as needed, and the operating system will allocate memory if it is available.

3. Compilation: This is the process of translating the program from a high-level language (like C or Java) to machine code that the computer can understand. While the compiler does need to understand how much memory the program will need for its static variables, it does not handle dynamic memory allocation.

So, dynamic memory allocation/linking of a program is done during execution.
