A priority intersection has a single-lane oneway traffic road crossing an undivided two-lane two-way traffic road. The traffic stream speed on the single lane road is $20$ kmph and the speed on the two-lane road is $50$ kmph. The perception-reaction time is $2.5$ s, coefficient of longitudinal friction is $0.38$ and acceleration due to gravity is $9.81 m/s^2$. A clear sight triangle has to be ensured at this intersection. The minimum lengths of the sides of the sight triangle along the two-lane road and the single-lane road, respectively will be

1. $50$ m and $20$ m
2. $61$ m and $18$ m
3. $111$ m and $15$ m
4. $122$ m and $36$ m

If you solve using SSD formula answer will be B and if using IRC 66 answer will be C, So both are correct
