Final Answer:
In 26 AD Tiberius permanently moves to the island of b) Capri.
Step-by-step explanation:
In 26 AD, Tiberius permanently moved to the island of Capri. This decision marked a significant shift in the Roman Empire's political landscape during Tiberius's rule.
Tiberius's choice of Capri was strategic. The island provided a secluded and secure location for the emperor, allowing him to govern with a degree of isolation from the political intrigues and potential threats in Rome. Capri's natural defenses and the relative difficulty of accessing the island made it an ideal retreat for Tiberius.
The move to Capri also had political implications. Tiberius's decision to govern from the island reflected his desire for greater control over the empire while minimizing the influence of the Senate and other political adversaries. This relocation allowed Tiberius to consolidate power and maintain a firm grip on the administration of the Roman Empire.
In conclusion, the answer is b) Capri, as Tiberius's permanent move to this island was a strategic decision that provided him with security, isolation, and increased control over the Roman Empire's affairs.
