This question belongs in chemistry.
c. C2H5OH
A common example of a nonelectrolyte is glucose, or C6H12O6. Glucose (sugar) readily dissolves in water, but because it does not dissociate into ions in solution, it is considered a nonelectrolyte; solutions containing glucose do not, therefore, conduct electricity.
D
Wave B because the compressions are more tightly packed, giving it a larger amplitude
I think A is the answer its hard to explain but i hope this helped.
