Best Answer Explained in Below-:

In C++, a destructor is a special member function that is automatically called when an object goes out of scope or is explicitly deleted, serving to clean up resources allocated to that object. The syntax for a destructor involves the tilde (`~`) symbol followed by the class name without any parameters.

Examining the options provided:

- **A) *vehicle ()**: This resembles a constructor rather than a destructor and uses an incorrect name case.
- **B) *vehicle (int value)**: This is also a constructor with a parameter, not a destructor.
- **C) ~ Vehicle ()**: This is the correct syntax for a destructor in C++. It uses the tilde followed by the class name (`Vehicle`), indicating that it is meant for cleaning up resources when a `Vehicle` object is destroyed.
- **D) ~ vehicle (int value)**: Similar to option B, this incorrectly includes a parameter and again uses an incorrect name case.

Thus, option C, **~ Vehicle ()**, is the only correct choice as it adheres to the C++ conventions for defining a destructor. It clearly indicates that it's a destructor for the `Vehicle` class and does not take any parameters, aligning perfectly with C++ syntax rules.
