Answer: The answer is C- comets!
Explanation: Callisto is composed mainly of rock and water ice, although other ices like ammonia ice and carbon dioxide ice may be present. Water ice occurs at the surface of Callisto so it would be comets.

B and C Reduce Emissions and Least fuel economy
Explanation:
Plug-in electric vehicles are related, fun and practical (also called electric cars or hybrid electric vehicles). We will reduce emissions and save you even money. EVs deliver more than individual advantages. EVs will allow the US to have a more diverse range of transportation fuel options. Last year the US used almost nine billion barrels of oil, of which two-thirds went into shipping. We are vulnerable to price increases and supply disruptions because of our dependence upon oil. EVs help reduce this threat, as almost all US electricity, including coal, nuclear, natural gas and renewables, is generated from domestic sources.Vehicles can also minimize the CO2 emissions, improve health, and reduce environmental damage that contribute to climate change and smog. Charging your EV for renewable, such as solar or wind, will further reduce these emissions. Link to a calculator on the right to the pollution disparity between the traditional and an EV. Discover how EV reduce pollution and their emissions during their life cycle.
Answer:
- <em>The function of an indicator in a titration is to </em><u>indicate the equivalence point.</u>
Explanation:
<em>Titration</em> is a procedure that uses the properties of the acid - base reactions to determine the mole concentration of an unknown solution from the known mole concentraion of other solution. One of the solution is the base and the other is the acid.
At the equivalence point, where the number of H⁺ ions is equal to the number of OH⁻ ions, there is a drastic change of the acidity (or alkalinity) of the solution.
Then, the chemical <em>indicators</em> are substances that change color at the equivalence point, telling the chemist that the equivalence point has been reached and the titration has finished.
