The leather industry in Punjab is primarily concentrated in:

The correct answer is: b) Ludhiana.

Ludhiana is the largest city in the Indian state of Punjab. It is known as the “Manchester of India” because of its textile industry. The city is also home to a large leather industry. The leather industry in Ludhiana is primarily concentrated in the Haibowal area of the city. The Haibowal leather market is one of the largest leather markets in Asia. It is home to over 10,000 leather tanneries and leather goods manufacturers. The leather industry in Ludhiana employs over 500,000 people. The industry contributes significantly to the economy of Ludhiana and Punjab.

The other options are incorrect because:

• Jalandhar is a city in the Indian state of Punjab. It is known for its textile industry. The city is also home to a large leather industry. However, the leather industry in Jalandhar is not as large as the leather industry in Ludhiana.
• Amritsar is a city in the Indian state of Punjab. It is known for its Golden Temple, a major Sikh pilgrimage site. The city is also home to a small leather industry. However, the leather industry in Amritsar is not as large as the leather industry in Ludhiana.
• Mohali is a city in the Indian state of Punjab. It is a planned city that was developed in the 1970s. The city is home to a number of educational institutions and IT companies. However, the city does not have a significant leather industry.
