Which one of the following is true about cometsGroup of answer choicesA comet is an icy, small Solar System bodyMost comets arenormally found in the outskirts of our solar systemComets have tail that points towards the SunComets have comparable size with planetsA and B

To determine which statement about comets is true, let's analyze each option step by step:

A. "A comet is an icy, small Solar System body."

• This statement is true. Comets are composed of ice, dust, and rocky material and are considered small bodies within the Solar System.

B. "Most comets are normally found in the outskirts of our solar system."

• This statement is also true. Comets typically originate from regions such as the Kuiper Belt and the Oort Cloud, which are located in the outer parts of the Solar System.

C. "Comets have a tail that points towards the Sun."

• This statement is false. A comet's tail actually points away from the Sun due to the pressure of the solar wind and radiation.

D. "Comets have comparable size with planets."

• This statement is false. Comets are much smaller than planets.

E. "A and B"

• Since both A and B are true, this option is correct.

Therefore, the correct answer is: E. A and B
