Trolley
Ohe
Motor Trolley
None of these
Answer is Wrong!
Answer is Right!
The correct answer is: A. Trolley.
A height gauge is a device used to measure the height of an object. It is typically used to ensure that objects are installed at the correct height, for safety reasons. For example, a
height gauge may be used to ensure that a trolley is installed at the correct height, so that it does not collide with overhead obstacles.The other options are incorrect because they are not objects that can be measured by a height gauge. An ohe is a type of overhead power line, and a motor trolley is a type of vehicle that travels on rails. Neither of these objects can be measured by a height gauge.
