Explanation:

To solve this, we analyze each option:

• "motion" is a general term for movement, not defined by magnitude and direction in this specific sense.
• "vector" is defined as a quantity with both magnitude (size) and direction (e.g., velocity, force).
• "speed" is a scalar (only magnitude, no direction).
• "reference point" is a location for comparison, not a quantity with magnitude and direction.

Answer:

B. vector (assuming the options are labeled as A. motion, B. vector, C. speed, D. reference point; if labels differ, adjust to the correct label with "vector" as the text)
