Official Solution & Explanation:
Correct Answer: Option A(संवेग)
संवेग ($\vec{p} = m\vec{v}$) एक सदिश राशि (Vector quantity) है, क्योंकि इसकी दिशा वस्तु के वेग की दिशा में होती है। दाब, ऊर्जा और कार्य अदिश राशियां हैं।
Momentum ($\vec{p} = m\vec{v}$) is a vector quantity having both magnitude and the direction of velocity. Pressure, energy, and work are scalar quantities.
