The given graph is an F-t graph, where F is force and t is time.

From Newton's second law, $F = ma$ .

Therefore, acceleration $a = F / m$ .

Since the mass $m$ of the particle is constant, the acceleration is directly proportional to the force ( $a \propto F$ ).

From $t = 0$ to $t = t_{1}$ , the force F is increasing linearly, so the acceleration is also increasing linearly.

After $t_{1}$ , the force F is constant, which means the acceleration is also constant.

Final Answer: The final answer is C
