A, B & D only

PYQPulse · Answer

Explanation: Warming ketchup makes it flow because liquids become less viscous at higher temperature: molecular kinetic energy increases with temperature and counteracts intermolecular forces. Liquid resistance to flow DECREASES with temperature (C is wrong). Correct: A, B & D. Answer: (3).
