Final answer:
Liquid A is less viscous than liquid B.
Step-by-step explanation:
The viscosity of a liquid is a measure of its resistance to flow. Liquids with higher viscosity flow more slowly, while liquids with lower viscosity flow more freely. In this case, liquid A takes 24 seconds to pour out, whereas liquid B takes 68 seconds.
Since liquid A takes less time to pour out, it has a lower viscosity compared to liquid B. Therefore, the correct statement about liquid A is that it is less viscous than liquid B (option B).
