Option A is correctly matched: The 3 Corps (Spear Corps) is headquartered at Rangapahar Military Station in Dimapur, Nagaland. It operates under the Eastern Command and handles counter-insurgency and border defense in the Northeast.

Option B is correctly matched: The 4 Corps (Gajraj Corps) is headquartered in Tezpur, Assam. It operates under the Eastern Command and is primarily responsible for defending the Line of Actual Control (LAC) in Arunachal Pradesh.

Option C is correctly matched: The 14 Corps (Fire and Fury Corps) is headquartered in Leh, Ladakh. It operates under the Northern Command and guards the Kargil-Leh frontiers with China and Pakistan, as well as the Siachen Glacier.

Option D is incorrectly matched: The 33 Corps (Trishakti Corps) is headquartered in Sukna (near Siliguri), West Bengal, and not in Srinagar.
