The small bodies that are hardest to tell apart because they are made of similar materials are asteroids and meteoroids.

If a scientist examines a sample of an object from the solar system that includes ice, the sample most likely comes from a comet.

To determine which of the given options is correct, we need to understand the characteristics of the objects mentioned.

Dwarf planets are celestial bodies that are similar to planets but have not cleared their orbit of other debris, such as asteroids or comets.

Comets are small bodies that are made up of ice, dust, rock, and other organic compounds. They often have a noticeable coma (a fuzzy or hazy atmosphere around the nucleus) when they get closer to the sun.

Asteroids are rocky objects that orbit the sun, primarily found in the asteroid belt between Mars and Jupiter. They are made up of various types of rock and metal.

Meteoroids are small rocky or metallic debris in space.

From the given options, the hardest to tell apart because they are made of similar materials are asteroids and comets. Both asteroids and comets can contain rock and metal. While comets also have ice and organic compounds, it is not mentioned that the sample contains organic compounds, making a comet the most likely answer.

Therefore, the sample mentioned in the question most likely comes from a comet.
