Identifying the Urban Scheme's Anniversary

The question asks to identify the major urban development scheme in India that celebrated its 10th anniversary in the year 2025.

Calculating the Launch Year

To find the scheme, we need to determine its launch year. If a scheme celebrated its 10th anniversary in 2025, it must have been launched 10 years prior.

Calculation: Launch Year = 2025 - 10 = 2015.

Verifying the Scheme

We need to identify which of the given urban development schemes was launched in 2015.

• Smart City Mission: Launched on June 25, 2015.
• Prime Minister Awas Yojana (PMAY): Launched in 2015, but the specific urban component (PMAY-U) was launched in 2015 replacing the previous scheme. The overall anniversary context usually refers to the main mission launch.
• Atal Mission for Rejuvenation and Urban Transformation (AMRUT): Launched in 2015.
• Swachh Bharat Abhiyan: Launched on October 2, 2014.

Both Smart City Mission and AMRUT were launched in 2015. However, the Smart City Mission is widely recognized for its foundational 10-year milestone being celebrated around 2025, focusing on transforming selected cities into smart cities.

Conclusion

Based on the launch year calculation (2015) and the common understanding of major urban initiatives, the Smart City Mission is the scheme celebrating its 10th anniversary in 2025.

Therefore, the correct option is the Smart City Mission.
