Propolis Cognitive Error Autopsy

Official Correct Choice:
Option C: 2 m
Concept: Coordinate Displacement.

Formula: \(\Delta x = 10 - 12 = -2\text{ m}, \Delta y = 15 - 15 = 0\text{ m}\)

Solution: Absolute scalar distance from origin = \(|-2| = 2\text{ meters}\).

Why other options are incorrect:

Option A: Assumes complete return to origin.
