${\tt{\green{\underline{\underline{\huge{ANSWER:—}}}}}}$

Question:—

⠀⠀⠀⠀If a particle executes uniform ⠀⠀⠀⠀circular motion, choose the ⠀⠀⠀⠀correct statement .

⠀⠀⠀⠀a) The velocity and speed are ⠀⠀⠀⠀⠀⠀constant.

⠀⠀⠀⠀b) The acceleration and speed ⠀⠀⠀⠀⠀⠀are constant.

⠀⠀⠀⠀c) The velocity and acceleration ⠀⠀⠀⠀⠀⠀are constant.

⠀⠀⠀⠀d) The speed and the magnitude ⠀⠀⠀ ⠀ of acceleration are constant.

Solution:—

• In uniform circular motion, speed is constant.
• In uniform circular motion, velocity is variables because at every point on the circle, the direction of velocity is tangential. So, it's direction changes and hence velocity also changes.
• In uniform circular motion, acceleration is also variable because at every point it's direction changes.
• In uniform, circular motion, Magnitude of velocity that means speed changes.
• In uniform, circular motion, Magnitude of acceleration also changes.

So, On observing above statements,

The correct answer is,

⠀⠀⠀⠀d) The speed and the magnitude ⠀⠀⠀⠀⠀⠀of acceleration are constant.
