Which of the following are hydrophilic petrolatum bases?

Explanation:
Hydrophilic petrolatum bases are petrolatum-based emulsions that can mix with water, allowing incorporation of aqueous medications. Aquabase and Aquaphor fit this description because they are emulsified bases containing water (and usually humectants or emulsifiers) that are washable with water. They enable adding aqueous drugs and provide moisture while still retaining a petrolatum-like feel. White petrolatum and white vaseline are pure petrolatum, which is hydrophobic and occlusive; it does not mix with water. Yellow ointment is also primarily petrolatum with wax and mineral oil, making it largely hydrophobic as well.
