Explanation:

Recently, Union Minister for Road Transport & Highways inaugurated the breakthrough event of Chamba Tunnel under Chardham Pariyojana. Border Roads Organisation (BRO) achieved this major milestone by digging up a 440 m long Tunnel below the busy Chamba town on Rishikesh-Dharasu road Highway (NH 94). Opening of this tunnel will ease out congestion though the Chamba town and reduce the distance by one kilometre. This Project will be completed by October 2020. Under prestigious Chardham Project costing around Rs 12,000 Crore with approximate length of 889 Km, BRO is constructing 250 Km of National Highways leading to holy shrine Gangotri and Badrinath. Hence option 1st is correct.
