$$x(t)$$ is a real valued function of a real variable with period $$T.$$ Its trigonometric. Fourier Series expansion contains no terms of frequency
$$\omega = 2\pi \left( {2k} \right)/T;\,\,k = 1,2,........$$ Also, no sine terms are present. Then $$x(t)$$ satisfies the equation
A
$$x\left( t \right) = - x\left( {t - T} \right)$$
B
$$x\left( t \right) = x\left( {T - t} \right) = - x\left( { - t} \right)$$
C
$$x\left( t \right) = x\left( {T - t} \right) = - x\left( {t - T/2} \right)$$
D
$$x\left( t \right) = x\left( {t - T} \right) = - x\left( {t - T/2} \right)$$
