Explanation
The diagonal elements of a stiffness matrix must be positive (i), ensuring structural stability, while the diagonal elements of a flexibility matrix must also be positive (iii). Therefore, the correct combination is (i) and (iii). The other options involve negative diagonal elements, which are not characteristic of stable structures.
