The Figure Represents the Velocity and the Acceleration of a Particle

The figure represents the velocity and the acceleration of a particle moving clockwise in a circle of radius 25.0 cm.At a certain instant of time,the magnitude of its acceleration,a = is 16.0 m/s² and it makes an angle $\theta$ = 20 ^$\circ$ with position vector as shown in the figure.At this instant,find the speed,v = of the particle.

A) 4.01 m/s
B) 3.29 m/s
C) 2.12 m/s
D) 1.94 m/s
E) 0.235 m/s
