Answer: (A)

Dynamometer

(A) Dynamometer- It is an instrument/device used for measuring mechanical force or power transmitted by a rotating shaft. For example, it is used to calculate the power produced by a motor or an engine in agricultural fields

(B) Hydrometer- It is a device used for measuring the relative density of liquids. It is made up of a thin glass tube and consists a bulb which floats upright.

(C) Galvanometer- It is a device used for measuring or detecting the flow of electric current through an electric circuit.
