The Earth stays in orbit around the Sun because:
The Sun's gravity pulls on the EarthThis is only part of the answer.
The Earth's gravity pulls on the SunThis is only part of the answer.
The gravity of the Sun and the Earth pull on each otherYes! The gravitational attraction between the Earth and the Sun is a result of both the Sun pulling on the Earth and the Earth pulling on the Sun.
Gravity does not keep the Earth in its orbit.No. Without the pull of gravity, the Earth would continue moving in a straight path instead of curving around the Sun.

SC.8.E.5.9 Explain the impact of objects in space on each other including: 1. the Sun on the Earth including seasons and gravitational attraction 2. the Moon on the Earth, including phases, tides, and eclipses, and the relative position of each body.
SC.6.P.13.2 Explore the Law of Gravity by recognizing that every object exerts gravitational force on every other object and that the force depends on how much mass the objects have and how far apart they are.
