Given a real valued function y (t) with period T. Its trigonometric Fourier series expansion contains no term of frequency ω = 2π \(\frac{(2k)}{T}\); where, k = 1, 2….. Also no terms are present. Then, y(t) satisfies the equation ____________

• A. y (t) = y (t+T) = -y (t+\(\frac{T}{2}\))
• B. y (t) = y (t+T) = y (t+\(\frac{T}{2}\))
• C. y (t) = y (t-T) = -y (t-\(\frac{T}{2}\))
• D. y (t) = y (t-T) = y (t-\(\frac{T}{2}\))
