How can two linearly polarized Yagi antennas be used to produce circular polarization?

1. AStack two Yagis to form an array with the respective elements in parallel planes fed 90 degrees out of phase
2. BStack two Yagis to form an array with the respective elements in parallel planes fed in phase
3. CArrange two Yagis on the same axis and perpendicular to each other with the driven elements at the same point on the boom and fed 90 degrees out of phase
4. DArrange two Yagis collinear to each other with the driven elements fed 180 degrees out of phase
