Option 4: Statement I is false but Statement II is true.

In option 4, it states that Statement I is false but Statement II is true. This means that the first statement, which says that King Ashoka abolished capital punishment and disbanded his army, is incorrect. King Ashoka is often regarded as one of the greatest emperors of ancient India, and it is true that he ruled with a philosophy of non-violence and compassion. However, during his reign, Ashoka did not abolish capital punishment or disband his army. In fact, he had a large and well-organized army that helped him maintain and expand his empire.

On the other hand, Statement II is true. After the brutal Kalinga War, in which a large number of people were killed, Ashoka experienced remorse for the violence and suffering caused by the war. This led him to embrace Buddhism and adopt a policy of non-violence. Ashoka became a devoted follower of Buddhism and worked to spread its teachings throughout his empire. He implemented policies of tolerance, peace, and moral conduct based on Buddhist principles.

Therefore, option 4 is the correct answer, as Statement I is false and Statement II is true.
