A lunar eclipse occurs when the Earth passes between the Sun and the full Moon, with the Moon passing through the Earth's shadow. Therefore, the phase of the Moon must be full. Additionally, the nodes of the Moon's orbit - the points where the Moon's orbit intersects the Earth's orbital plane - must be nearly aligned with the Earth and the Sun for a lunar eclipse to occur. Therefore, the correct conditions are B) The phase of the Moon must be full, and the nodes of the Moon's orbit must be nearly aligned with Earth and the Sun.
