Answer : Accelerometer detects the changes in velocities.

Explanation :

We know that the velocity of an object is defined as the rate of change of displacement. Velocity is a vector quantity i.e having both magnitudes as well as direction.

The rate of change of velocity of a body is called its acceleration. If u is the initial velocity and v is the final velocity of a body. Then the relation for acceleration is :

A device that detects the acceleration (changes in velocity) are Accelerometer. It finds the magnitude and direction of proper acceleration.

there is no correct list among the choices you've provided.

the list might look something like this:

-- baby human

-- piccolo

-- flute

-- soprano singer

-- trumpet

-- tenor singer
