Answer:

• Liquid A

Why?

• The greater the inter molecular forces in a substance the greater the attraction the molecules of the substance have for other molecules.
• The greater the inter molecular forces in a substance the greater the attraction the molecules of the substance have for other molecules.Because the molecules in liquid A have a greater attraction for each other the molecules in liquid A will "stick" together.

• The more the molecules "stick" together the greater the viscosity.

am I right?
