  2. half the existing value

  3. the same as existing value

  4. indeterminate value

C Correct answer
Explanation

 For a linear elastic frame stiffness is the force required for unit deflection when stiffness of the elastic frame is doubled then deflection will be reduced to half for the constant applied force.
