What husband of Boudicca willed his land to Rome?

The husband of Boudicca who willed his land to Rome is Prasutagus. This historical figure was the king of the Iceni tribe in ancient Britain. Upon his death, he attempted to secure a peaceful relationship with the Roman Empire by leaving his estate jointly to his two daughters and the Roman emperor. This decision reflects his strategy to maintain his kingdom's independence while still aligning with the ruling powers of the time. However, this act of loyalty did not yield the intended peace, as the Romans disregarded his wishes and mistreated his family, ultimately leading to the famous rebellion led by Boudicca against Roman rule.

The other names listed do not have any historical connection to Boudicca or the Iceni tribe in relation to the Roman Empire, which confirms that Prasutagus is the only correct choice in this context.
