Concept:
To accurately locate any geographical point on Earth relative to primary reference parallels—such as the Equator (\(0^\circ\) latitude), the Tropic of Cancer (\(23^\circ 30'\text{ N}\)), or the Tropic of Capricorn (\(23^\circ 30'\text{ S}\))—we must examine the precise latitudinal coordinates of the region. The country of India is positioned entirely within the Northern and Eastern hemispheres of the globe.
Step 1:
Let us examine the exact geographic, latitudinal limits of the mainland of India:
• The Indian mainland extends vertically between latitudes
\(8^\circ 4'\text{ N}\) in the south to
\(37^\circ 6'\text{ N}\) in the north.
• Kanyakumari (formerly known historically as Cape Comorin), located at the southern tip of the state of Tamil Nadu, represents the southernmost extremity of this peninsular mainland.
• Its precise geographic position is located exactly at approximately
\(8^\circ 4'\text{ N}\) latitude.
Step 2:
Now, let us evaluate the positions of the major global reference lines relative to Kanyakumari's position at \(8^\circ 4'\text{ N}\):
• The Equator (\(0^\circ\) Latitude): Since Kanyakumari is at a latitude of \(8^\circ 4'\text{ N}\), it means it is located exactly \(8^\circ 4'\) angular distance north of the primary zero-degree parallel. Therefore, Kanyakumari lies North of the Equator. This validates option (C).
• The Tropic of Cancer (\(23^\circ 30'\text{ N}\) Latitude): The Tropic of Cancer runs right through the geographical center of India, passing through eight states (Gujarat, Rajasthan, Madhya Pradesh, Chhattisgarh, Jharkhand, West Bengal, Tripura, and Mizoram). Because \(8^\circ 4'\text{ N}\) lies numerically below \(23^\circ 30'\text{ N}\), Kanyakumari is situated completely
South of the Tropic of Cancer, which directly rules out option (A).
• The Tropic of Capricorn (\(23^\circ 30'\text{ S}\) Latitude): This parallel is located far down in the Southern Hemisphere. Because the entirety of India’s mainland lies strictly above \(0^\circ\), options (B) and (D) are geographically impossible for any territory of mainland India.
Consequently, we conclude that Kanyakumari is located North of the Equator.
