The question was posed to me in an interview for internship.

The doubt is from Aircraft Materials in portion Testing Aircraft Materials of Aerospace Materials & Processes

Answer 1

The correct choice is (b) application of pressure and blow from a hammer

To elaborate: The bending in the bending test is usually achieved by either applying a constant source of pressure or by delivering blows from a hammer. The usage of the hammer creates a much higher impact on the specimen than the other method.
