Explanation:

Agra is renowned globally for its exquisite marble work, primarily due to the iconic Taj Mahal, which is constructed entirely of white marble and features intricate Pietra Dura (marble inlay) craftsmanship. The city has a rich tradition of marble artistry, with numerous artisans specializing in marble carving, inlay, and sculpture, making it the epicenter for marble crafts in Uttar Pradesh. Lucknow, on the other hand, is famous for its Chikankari embroidery and historical monuments, not marble. Mirzapur is known for its carpet weaving industry and brassware, while Meerut is recognized for its sports goods manufacturing and musical instruments. Therefore, only Agra is distinctly famous for its marble.
