Largest concentration of software and business process outsourcing industry in U.P. is at

The correct answer is C) Noida. The Noida-Greater Noida belt in Gautam Buddh Nagar district has the largest concentration of software and ITeS/BPO units in Uttar Pradesh. Its base was laid by the Noida Special Economic Zone, set up in 1984, and the STPI unit there, along with the Sector 62 and Sector 125 IT clusters, drew global firms to the area.

Why the others are weaker:

• Meerut is known for sports goods, surgical instruments and sugar, not for IT or BPO clusters.
• Kanpur is an industrial, leather and textile city. It has some IT presence but nothing close to Noida's scale.
• Varanasi has an STPI centre and a few IT parks, but it is primarily a cultural and handloom centre.

Core concept: UP's IT geography is clustered around the Delhi-NCR spillover zone. Lucknow's IT footprint has expanded since 2016, so treat Noida's lead as a position for the exam year and check current data before using it as a permanent fact. This links to the Mains theme of regional disparities and urban employment.

Trap: candidates pick Lucknow because it is the capital and a visible IT centre, but the question asks for the largest concentration, which is Noida.
