Option D is correct.

In Mountainous and Steep terrain the total width of Road way or Formation width = 3.75 ( for plain terrain ) + both sides shoulders of 1.25m = 3.75 + 2*1.25 = 6.25m.

IRC suggested as the roadway width for mountainous and steep terrain for NH single lane road is 6.25.

So, ans C is correct.

For plane 7.9m (3.6+3.6+ 0.7) is 7.9.
For hills 6.25m (3.75+3.75+1.25).

As per IRC:

The total width of carriage way for single lane is 3.75 (NH/SH), for two-lane its 7.0, for multi-lane its 3.50/lane.

For MDR /ODR : 3.50, for two LANE 5.5,
for VR: 3.0.
So, option A is correct.
