Which of the following is/are basically meant to be deployed in the northern borders of India for monitoring the borders and also to stop smuggling and illegal immigration ? 1. Assam Rifles 2. Border Security Force 3. Indo Tibet Border Police 4. National Security Guards Select the correct answer using the code given below:

The Indo-Tibetan Border Police (ITBP) is the primary Central Armed Police Force specifically mandated to guard India's northern borders along the Himalayas, stretching from the Karakoram Pass in Ladakh to Jachep La in Arunachal Pradesh. Its core duties include monitoring the border, preventing trans-border crimes, and curbing smuggling and illegal immigration in these high-altitude regions. While the Border Security Force (BSF) is responsible for the western and eastern borders with Pakistan and Bangladesh [2], and the Assam Rifles primarily manages the Indo-Myanmar border [4], the ITBP is the specialized force for the northern frontier. The National Security Guard (NSG) is an elite counter-terrorism unit and is not deployed for border guarding. Therefore, only the ITBP (Statement 3) fits the specific description of being deployed on the northern borders for monitoring and anti-smuggling operations.
