The Young's modulus of elasticity of steel, is

Option B Accurate answer

While practically used value is 200KN/mm^2

In other site & books it is 200 kN/mm^2. plz correct this or change your statement that maximum young modulus of steel is 275 kN/mm^2. We always use 200 kN/mm^2 for safe while designing. So minimum is 200 kN/mm^2 and max is 275 kN/mm^2.
You should retype because examiners take question from the different sites where everyone has own Answer.

OPTION B IS CORRECCT

Option B is correct answer not D.
Your knowledge is low

Option B is correct answer
