The young 's Modulus for a perfect rigid body as the perfectly rigid body is one for which strain is zero whatever may be the stress. 

Young's modulus is defined as = stress / strain

Since strain is zero, Young's modulus for a perfectly rigid body is infinity and young modulus for a perfect infinity thereof.
