Which one of the following is under the control of the Ministry of Defence ?

The Rashtriya Rifles (RR) is a specialized counter-insurgency force that operates under the control of the Ministry of Defence [2]. Formed in 1990 to address internal security and militancy in Jammu and Kashmir, it is composed of personnel drawn from the Indian Army on deputation [2]. While it performs internal security duties often associated with paramilitary forces, it remains under the administrative and operational command of the Indian Army and the Ministry of Defence [2]. In contrast, the Indo-Tibetan Border Police (ITBP), National Security Guard (NSG), and Sashastra Seema Bal (SSB) are Central Armed Police Forces (CAPFs) that function under the administrative control of the Ministry of Home Affairs [1]. The NSG, specifically, is a special force operating under the Home Ministry for counter-terrorism tasks [1].
