Explanation:

• The Milky Way and Andromeda Galaxy are galaxies, not boundaries of the solar system.
• Earth's atmosphere is part of Earth, not the boundary of the solar system.
• The Kuiper Belt is a region of icy bodies beyond Neptune, and the Oort Cloud is a hypothesized spherical cloud of icy objects surrounding the solar system, often considered as the outer boundaries of the solar system.
• The sun's heliosphere is the bubble-like region created by the solar wind, but it is not the commonly - accepted outer boundary in terms of the solar system's extent compared to the Kuiper Belt and Oort Cloud.

Answer:

B. Kuiper Belt and Oort Cloud
