The Kargil War, a conflict between India and Pakistan in 1999, concluded following the Washington Agreement. This agreement was reached between US President Bill Clinton and Pakistani Prime Minister Nawaz Sharif, where Pakistan committed to withdrawing its forces from the Kargil sector, leading to the cessation of hostilities and restoration of the Line of Control.

• The Tashkent Agreement ended the 1965 Indo-Pak War.
• The Karachi Agreement established the ceasefire line in Kashmir after the 1948 war.
• The option 'None of these' is incorrect as the Washington Agreement directly led to the war's end.

The Washington Agreement was crucial in de-escalating the Kargil conflict.
