Statement I: A cyclist is moving on an unbanked road with a speed of `7 kmh^(-1)`and takes a sharp circular turn along a path of radius of 2m without reducing the speed. The static friction coefficient is 0.2. The cyclist will not slip and pass the curve. `(g=9.8 m//s^(2))`.
Statement II: If the road is banked at an angle of `45^(@)` cyclist can cross the curve of 2m radius with the speed of `18.5 kmh^(-1)` without slipping.
In the light of the above statements, choose the correct answer from the options given below.

A

Statement I is correct and statement II is incorrect

B

Both statement I and statement II are false

C

Both statement I and statement II are true

D

Statement I is incorrect and statement II is correct
