D is true because NO2 is a catalyst, and a catalyst is a compound which makes a reaction occur faster (not necessarily more effectively, creating more product, but it decreases the amount of time it takes).
Answer:
Boiling point of solution is
Explanation:
Cane sugar is a non-volatile solute.
According to Raoult's law for a non-volatile solute dissolved in a solution-

Where,
is elivation in boiling point of solution,
is ebbulioscopic constant of solvent (how much temperature is raised for dissolution of 1 mol of non-volatile solute) and m is molality of solution.
Here, 
610 g of cane sugar =
moles of cane sugar
= 1.78 moles of cane sugar
So, molality of solution (m) = 
Plug in all the values in the above equation, we get-

So, boiling point of solution =
