Answer 1

Right choice is (c) Locating centre of bar stock

The explanation is: Scale and squaring head are used for measuring depth and height, and squaring operations. Scale and centre head are used for locating the centre. Part to be centred should place beneath the scale and against the sides of centre head for locating the centre.
