C. A baseball bat strikes a baseball.
Explanation:
Newton's second law of motion states that acceleration happens when force is applied on the mass.
<em>A baseball bat strikes a baseball is the best example of Newton's second law of motion because acceleration of the baseball is directly proportional to the force by which baseball bat hit it.</em>
Hence, the correct option is 'C. A baseball bat strikes a baseball.'
