Concept:Sayyid Said changed the political centre of his Omani empire to an East African island for trade and political reasons.
Explanation:Sayyid Said ruled a maritime empire that controlled both sides of the Indian Ocean.
By 1840, he decided to move his capital from Muscat, on the Arabian coast, to Zanzibar.
Zanzibar was a major trading hub for cloves, ivory, and slaves, so it gave him closer control over profitable East African trade routes.
He and his household settled there, and he declared Zanzibar the new capital of his empire.
This shift strengthened Omani influence along the East African coast and made Zanzibar an important commercial and political centre.
Answer:B. Zanzibar
