Official Correct Choice:
Option C: Both I and II
Concept:

The foundational capabilities of force as defined by Newton.

Solution:

  • A net external force produces an acceleration vector.


  • If this acceleration acts against motion, the object slows/stops (Statement I).


  • If it acts with motion, it speeds up (Statement I).


  • If the force acts perpendicular or diagonally to the current velocity (like gravity on a projectile or a steering wheel turning a car), it alters the path/direction (Statement II).


  • Therefore, both statements flawlessly describe classical force mechanics.


Why other options are incorrect:

Excluding either statement artificially ignores half of Newton's Second Law.
