A Correct answer
Explanation

When working with void pointers, you must manually increment by the size of the data type. Option A ptr = ptr + sizeof(myStruct) correctly advances the pointer by one struct size. Options B, C, and E are incorrect syntax or logic, and option D is not a standard function.
