A student is performing a recrystallization of Compound X. However, they are unsure what solvent(s) they should chose for their single-solvent or solvent-pair (two-solvent) recrystallization. You as the TA are tasked with assisting this student to ensure they have as successful an experiment as possible. As the TA, you should suggest the option that is the most reasonable. Using the information below, identify the appropriate solvent(s) to use in this recrystallization. Select all statements that apply.
Solubility of Compound X in varying solvents.

This student requires diethyl ether
This student should perform a single-solvent recrystallization for the best results.
This student should perform a solvent-pair recrystallization for the best results.
This student requires water
This student requires ethanol
No single solvent or pair of solvents from these options will work for this student.
