Correct option is C

The correct answer is (c) Only (i), (ii) and (iv) 
Explanation:
· (i) It passes through 17 countries including India, Saudi Arabia and China: This statement is correct. The Tropic of Cancer passes through 17 countries, including India, Saudi Arabia, China, Mexico, Algeria, Egypt, Mali, Mauritania, Niger, Libya, United Arab Emirates, Oman, Bangladesh, Myanmar, Taiwan, Bahamas, and Western Sahara.
· (ii) It is located at approximately 23.5° N latitude: This statement is correct. The Tropic of Cancer is an imaginary line of latitude situated at 23°26′13.5″ (or approximately 23.5°) North of the Equator. It marks the most northerly latitude at which the sun can be directly overhead at the Summer Solstice.
· (iii) It passes through 10 States in India: This statement is incorrect. The Tropic of Cancer passes through eight states in India, not 10. These states are Gujarat, Rajasthan, Madhya Pradesh, Chhattisgarh, Jharkhand, West Bengal, Tripura, and Mizoram.
· (iv) It crosses Mahi River twice in Madhya Pradesh and Gujarat: This statement is correct. The Mahi River is unique in India as it crosses the Tropic of Cancer twice. It originates in Madhya Pradesh, flows northwards crossing the Tropic of Cancer into Rajasthan, and then turns westwards into Gujarat, crossing the Tropic of Cancer for the second time before emptying into the Arabian Sea.
