Step 1: Understand the methods in LIST-I.
- **Gauss Seidel method** is a technique used for solving **Linear Algebraic Equations**.
- **Forward Newton method** is used for **Interpolation**.
- **Runge Kutta method** is a **Numerical Integration** technique.
- **Trapezoidal rule** is another method for **Numerical Integration**.
Step 2: Match the methods from LIST-I with their respective categories in LIST-II.
- A. Gauss Seidel method corresponds to **IV. Linear algebraic equations**.
- B. Forward Newton method corresponds to **I. Interpolation**.
- C. Runge Kutta method corresponds to **II. Non-linear Differential equation**.
- D. Trapezoidal rule corresponds to **III. Numerical Integration**.
Final Answer: \[ \boxed{\text{(C) A - III, B - I, C - II, D - I}} \]
