None of the above
Detailed Explanation
All three listed techniques are used for handling hash collisions.
Linear probing searches subsequent slots sequentially.
Quadratic probing uses increasing quadratic offsets to find another available position.
Separate chaining stores multiple collided entries in a separate collection associated with each bucket. Other techniques include
double hashing. Therefore, none of options A, B, or C is an invalid collision-resolution technique, making
None of the above the correct answer.
