Answer
BOTH of these.
Explanation
When there is a change in the shape of an object by bending, compressing or stretching, it means that there is a form of deformation happening. The force that causes this deformation can be categorized into two - either a single force or multiple forces. 1) "More than one force is applied to the object": Deformations can certainly occur when multiple forces are applied to an object - it can result in bending, compressing, stretching or even twisting in some cases. Here, the various forces do not essentially have to be equal and may be applied in a different direction. The ultimate behavior of the object results from the superposition effect of those forces. An opportunity to see such multi-force influenced deformation in action is in a stress experiment on a sample rod where it’s compressed or stretched by opposing forces or even gases or fluids pressure.2) "Only one force is applied to the object" : A single force when applied on an object, canundoubtedly lead to compression, stretching or bending. What matters here is where the force is applied and how it recognises itself to the resulting alteration in shape. For activity, when you extend a spring at one edge, it's caused by a single applied force, but deformation occurs nonetheless.Yet, it is not limited to one or the other of these conditions for deformation to occur. It means the parameter for force dedication to prescribe the deformity is not rigorously conditioned to be only one or more forces. Therefore, the right response could be satisfied by "BOTH of these".
