Show answer & explanation
Correct answer: B
Match each method with its standard convergence property. False Position is a bracketing method, so it has order 1 with guarantee of convergence: Q-III. Newton-Raphson has quadratic convergence near a simple root: R-II. Secant method has order of convergence about 1.62: S-I. Successive Approximation or fixed point iteration is generally order 1 and convergence is not guaranteed unless the iteration satisfies the required contraction condition: T-IV. Therefore the correct matching is Q-III R-II S-I T-IV.
