Consider the following statements with respect to Taj Trapezium Zone (TTZ)1.It is so named since it is located around the Taj Mahal and is shaped like a trapezoid. 2. The TTZ comprises monuments including three World Heritage Sites the Taj Mahal, Agra Fort and Qutub Minar. 3. It spreads over the state of Uttar Pradesh, Haryana and Rajasthan.

The Taj Trapezium Zone (TTZ) is a region in India that is specifically designated to protect the Taj Mahal and other historical monuments from pollution and environmental degradation. The name "Taj Trapezium Zone" is derived from the shape of the region, which is roughly trapezoidal, and its location around the Taj Mahal in Agra, Uttar Pradesh.

The TTZ is a critical area for conservation efforts because the Taj Mahal and other monuments within the zone are highly sensitive to pollution. The zone was established to ensure that the air quality and environmental conditions around these monuments are maintained at a level that prevents damage to the structures.

Regarding the statements in the question:

Statement 1 is correct. The Taj Trapezium Zone is indeed named for its trapezoid shape and its location around the Taj Mahal. The shape of the zone is a trapezoid, and it is centered around the Taj Mahal, which is the primary reason for the designation of this area.

Statement 2 is incorrect. While the Taj Mahal and Agra Fort are both World Heritage Sites located within the TTZ, Qutub Minar is not part of the TTZ. Qutub Minar is a separate World Heritage Site located in Delhi, not in the TTZ around the Taj Mahal.

Statement 3 is incorrect. The TTZ is entirely within the state of Uttar Pradesh and does not extend into Haryana or Rajasthan. The zone is confined to the area around Agra, which is in Uttar Pradesh.

Therefore, the correct answer is Option A, which states that only the first statement is correct. The other statements contain inaccuracies regarding the monuments included in the TTZ and the geographical extent of the zone.
