Answer:
B. Solid
Step-by-step explanation:
As the problem states, the stronger the cohesive forces of a substance, the more ordered that substance is.
Asking which state has the strongest cohesive forces is the same as asking which state is the most organized.
Solids are more organized than liquids (as solids have a definite shape and volume). Liquids are more organized than gases (as liquids have a definite volume).
