The correct answer is (a) Nagoya.
Nagoya is the third largest city in Japan, after Tokyo and Osaka. It is located in the Chubu region of the country, on the central Honshu island. Nagoya is a major industrial and manufacturing center, and is home to many factories and companies. The city is also a major transportation hub, with a large airport and a network of railways and highways.
Nagoya is sometimes called the “Manchester of the East” because of its industrial heritage. Manchester is a city in England that was once a major center of the textile industry. Like Manchester, Nagoya has a long history of manufacturing, and is home to many factories and companies.
The other options are incorrect because they are not major industrial centers. Tokyo is the capital of Japan and is a major financial and commercial center. Osaka is the second largest city in Japan and is a major port city. Sendai is the largest city in the Tohoku region of Japan and is a major transportation hub.
