Why is no real body truly rigid?

AReal bodies deform
BReal bodies dissolve
CReal bodies dislodge
DReal bodies disperse
Answer & Solution
Correct answer: A. Real bodies deform
1. Rigidity is an idealisation, not an observed fact. 2. Applying a force always changes a real shape a little. 3. No real body is truly rigid, since real bodies deform under the influence of forces. 4. So the answer is real bodies deform. _Source: syllabus Physics Part I, Ch 6 'Systems of Particles and Rotational Motion'_
