The correct answer is option 2: Surat and Patan.

The Patola weave is a traditional weaving technique that is known for its intricate and vibrant designs. It originated in Gujarat, India, and is famously done in two cities, Surat and Patan.

Surat, located in Gujarat, is known for its expertise in textile production. It has been a major center for weaving and dyeing fabrics for centuries. The Patola sarees made in Surat are known for their geometric patterns and vibrant colors.

Patan, another city in Gujarat, is also famous for its Patola weaving tradition. The Patola sarees made in Patan are known for their double ikat technique, where both the warp and weft threads are resist-dyed before weaving. This technique requires immense skill and precision.

While the other options mentioned in the question, such as Pochampally and Kanchipuram, Dacca and Benares, and Benares and Paithan, are renowned for their own styles of weaving and textiles, they are not traditionally associated with the Patola weave.

Therefore, the correct answer is option 2: Surat and Patan.
