The correct answer is Tropic of Cancer.

• The Tropic of Cancer is an imaginary line that passes through the center of India, at an angle of 23.50 degrees north of the Equator.
• It passes through 17 nations, one of them being India.
• In India, the Tropic of Cancer passes through eight states:
  • Gujarat (Jasdan), Madhya Pradesh (Shajapur), Rajasthan (Kalinjarh), Tripura (Udaipur), Chhattisgarh (Sonhat), Jharkhand (Lohardaga), West Bengal (Krishnanagar), and Mizoram (Champhai).
• The Mahi River is the only river in India that twice cuts the Tropic of Cancer, first in Madhya Pradesh, from where it flows to Rajasthan and for the second time, reaches Gujarat where it cuts.
• The closest city to the Tropic of Cancer is Udaipur in Tripura.
• The sunsets perpendicular to the Tropic of Cancer during the Summer Solstice, that is, on June 21, and on the 21st of December, the same thing happened in the southern hemisphere, in the Tropic of Capricorn.
• The Tropic of Capricorn does not pass through India.
• The Equator, the Tropic of Cancer, and the Tropic of Capricorn are three imaginary lines passing around the Earth's surface. At 23.5° north of the equator, the Tropic of Cancer is found.
