Answer 1

Hint: The Bosphorus strait is located in northwestern Turkey which is a narrow and natural strait waterway. It is an internationally significant waterway. This waterway divides Turkey by separating the Anatolia and Thrace. It also forms a continental boundary between Europe and Asia.

Complete answer:
Bosphorus strait is the world’s narrowest strait which is used for international navigation. The Bosphorus connects the Black Sea with the Marmara Sea. The maximum length of this strait is 31 km (19 mi). Its minimum width is 700 m (2,300 ft.) and the maximum depth is 110 m (3609 ft.). Except in the north, most of the shores of this strait are heavily settled and straddled by the city of Istanbul’s metropolitan population of about 17 million inhabitants extending inland from both the coasts. The Bosporus forms a Turkish strait together with the Dardanelles. This strait connects various seas as a maritime waterway. It is a crucial international waterway, in particular for the passage of the goods coming in from Russia. The deepest location of this strait is between Kanilli and Bebek with 110 m (360 ft.). Off Kadikoy Inciburnu and off Asiyan Point are the shallowest locations with 18 m (59 ft.) and 13 m (43 ft.) on the northward and southward routes respectively.

Thus, option (A) is correct.

Note: The Bosphorus strait not only connects the Black Sea and the Marmara Sea but also Aegean and the Mediterranean Sea by extension via the Dardanelles and by the Kerch Strait, it connects with the Sea of Azov.
