Let x(t) be a continuous time periodic signal with fundamental period T = 1 seconds. Let ak be the complex Fourier series coefficients of x(t), where k is integer valued. Consider the following statements about x(3t): 1. The complex Fourier series coefficients of x(3t) are ak where k is integer valued. 2. The complex Fourier series coefficients of x(3f) are 3ak where k is integer valued. 3. The fundamental angular frequency of x(3t) is 6π rad/s. For the three statements above, which one of the following is correct?

Answer: Option B
