Correct Answer
B. 80
Why is this the answer?
Per IRC 66:2011 Table 1, Stopping Sight Distance (SSD) for design speed 60 km/h = 80 m. Derived from SSD formula with V=60 km/h, t=2.5 s, f=0.40 gives ~77 m, rounded up to 80 m as the IRC design standard for this speed. IRC recommended SSD for 60 km/h is 80 m
