Correct answer: The Moon

Although the Sun is vastly more massive, the Moon is much closer to Earth, meaning its gravitational gradient across our planet is far stronger. This difference in pull stretches the oceans into a slight oval, creating two high tides and two low tides each day. When the Sun and Moon align during full and new moons, their combined forces produce exceptionally high tides known as spring tides.
