Triangle ABC has sides \(a, b, \text{ and } c\). For this triangle, four statements are made:

(i)  If \(b^2 = a^2 - c^2\), then \(\angle \text{B} = 90^{\circ}\)

(ii)  If \(c^2 = a^2 + b^2\), then \(\angle \text{C} = 90^{\circ}\)

(iii)  If \(a^2 = b^2 - c^2\), then \(\angle \text{B} = 90^{\circ}\)

(iv)  If \(b^2 = a^2 + c^2\), then \(\angle \text{A} = 90^{\circ}\)

From the statements above, the correct statements are ...

(A)  i and iii

(B)  ii and iv

(C)  ii and iii

(D)  i and iv
