Solution

The correct option is D $4 m / s$
After half revolution, the cyclist will be on the opposite side of the diameter from the point where he started
So his displacement = diameter = $2 \times 120 m = 240 m$
time taken is $1 m i n = 60 s$ so average velocity $v = \frac{240 m}{60} = 4 m / s$

So, the correct answer is '4m/s'.
