Match List-I with List-II in regard to Fourier series of periodic f(t) and select the correct answer using the options given below:
| List-I (Properties) | List-II (Characteristics of the trigonometric form) |
| a. f(t) + f(-t) = 0 | 1. Even harmonics can exist |
| b. f(t) - f(-t) = 0 | 2. Odd harmonics can exist |
| c. $${\text{f}}\left( {\text{t}} \right) + {\text{f}}\left( {{\text{t}} - \frac{{\text{T}}}{2}} \right) = 0$$ | 3. The dc and cosine terms can exist |
| d. $${\text{f}}\left( {\text{t}} \right) - {\text{f}}\left( {{\text{t}} - \frac{{\text{T}}}{2}} \right) = 0$$ | 4. sine terms can exist |
| 5. cosine terms of even harmonics can exist |
