The best answer that describes displacement is:
Displacement is a scalar quantity which accounts for how far away an object is after a period of time has elapsed from its initial starting point.
However, it's important to note that this definition incorrectly classifies displacement as a scalar quantity. Displacement is actually a vector quantity because it has both magnitude and direction. So, while the statement is partially correct in describing displacement as a measure of how far an object is from its initial position, it should correctly identify displacement as a vector quantity.
