If a material had a modulus of elasticity of \[2.1\times {{10}^{6}}\text{kgf/c}{{\text{m}}^{\text{2}}}\] and a modulus of rigidity of \[0.8\times {{10}^{6}}\text{kgf/c}{{\text{m}}^{\text{2}}}\] then the approximate value of the Poisson's ratio of the material would be:

A) 0.26                             

B) 0.31

C) 0.47                             

D) 05
