The correct answer is option 'D', None.

Explanation:
Shapur I, the Sassanian ruler, claimed to have annihilated a Roman army of 60,000, but this claim is not historically accurate. There is no evidence to support the existence of such a large Roman army being defeated by Shapur I.

Historical Background:
Shapur I was the second ruler of the Sassanian Empire, which was a major power in the region during the 3rd century CE. The Sassanian Empire was located in modern-day Iran and was a rival to the Roman Empire. The Sassanians and Romans engaged in several conflicts during this period, known as the Roman-Sassanian Wars.

Shapur I's Military Victories:
Shapur I was known for his military campaigns and achieved significant victories against the Roman Empire. He successfully captured several Roman cities, including Antioch, which was a major Roman stronghold. Shapur I also defeated several Roman emperors in battle, such as Valerian, whom he captured and kept as a prisoner for the rest of his life.

Claims of Annihilating a Roman Army:
While Shapur I had many military successes against the Romans, there is no historical evidence to support his claim of annihilating a Roman army of 60,000 soldiers. This claim is likely an exaggeration or propaganda to enhance his reputation as a powerful ruler. It is common for rulers throughout history to exaggerate their military achievements for political purposes.

Historical Sources:
The primary historical sources for this period, such as Roman and Persian records, do not mention the annihilation of such a large Roman army by Shapur I. These sources provide detailed accounts of the Roman-Sassanian Wars, but none mention a battle of this magnitude.

Conclusion:
In conclusion, while Shapur I was a successful ruler and military leader, there is no historical evidence to support his claim of annihilating a Roman army of 60,000 soldiers. This claim is likely an exaggeration or propaganda to enhance his reputation.
