Explanation:

• IPS officer Charu Sinha has become the first woman commander to head the Central Reserve Police Force (CRPF) formation in the Kashmir Valley.
• Sinha, a 1996-batch officer of the Telangana cadre, has been appointed as the Inspector General (IG) of CRPF’s Srinagar sector that oversees the deployment of the paramilitary forces’ battalions in Srinagar city of the Union Territory of Jammu and Kashmir.
• A few years ago, Sonali Mishra, IPS officer of the 1993-batch Madhya Pradesh cadre, had served as the IG of another paramilitary force, the Border Security Force, in Kashmir.

Hence option 3rd is correct.
