Consider the following statements regarding the applicability of displacement and force methods in structural analysis. Which pair of statements is accurate?

Explanation

Statement (i) claims the displacement method is preferable when the degree of kinematic indeterminacy exceeds that of static indeterminacy. Statement (ii) suggests the displacement method is better when the degree of kinematic indeterminacy is less than static indeterminacy. Statement (iii) indicates the force method is more suitable when static indeterminacy is higher than kinematic indeterminacy. Statement (iv) states the force method is advantageous when static indeterminacy is lower than kinematic indeterminacy. The correct choice is option D, which pairs statements (ii) and (iv), reflecting the correct conditions for applying the displacement and force methods.
