An unstable vibratory motion due to combined bending and torsion which occurs in flexible plate like structures is called Correct Answer Flutter

Concept:

Flutter: It is an oscillatory motion that results from the coupling of aerodynamic forces with the elastic deformation of a structure. It is often the results of combined bending and torsion and effects plate like structures. For e.g. a sign boards and suspension bridges decks.

Galloping: It is a typical instability of flexible, lightly damped structures. Although many two-dimensional bodies can experience galloping episodes, this kind of instability seems to appear more rather in bluff bodies than in streamlined ones.

Ovalling: It refers to the distortion of body into an oval shape.

Oscillation: It refers to the repeated back and forth movement of something between two positions or states. An oscillation can be a periodic motion that repeats itself in a regular cycle. For e.g. a wave with perpetual motion as in the side-to-side swing of a pendulum.
