This question is asking about the greatest achievement of King Josiah of Judah. The options are rebuilding the Temple, sweeping reforms of the religious life of his people, curtailing the Assyrian aggressions, and training a worthy successor before his death. The correct option is B, which is sweeping reforms of the religious life of his people.

King Josiah was a faithful king of Judah who ruled from around 640 to 609 BC. He was known for his devotion to God and his efforts to reform the religious practices of his people. His greatest achievement was the sweeping reforms he implemented in Judah, which included the restoration of the Temple and the re-establishment of the Passover celebrations. He also removed pagan idols and altars from the land and enforced the laws of the Torah.

While rebuilding the Temple was a significant achievement, it was not King Josiah's greatest achievement. Likewise, curtailing the Assyrian aggressions and training a worthy successor before his death were important accomplishments, but they were not his greatest achievement. It was King Josiah's efforts to reform the religious life of his people that earned him the title of one of the most righteous kings of Judah.

In summary, the correct option for the greatest achievement of King Josiah of Judah is B, which is sweeping reforms of the religious life of his people. This was achieved through his devotion to God and his implementation of reforms that restored the Temple, re-established Passover celebrations, and removed pagan idols and altars from the land.
