The correct option is A Water > Honey > Toothpaste
The fluidity of any liquid is determined by how easily it flows. To understand which substance will be the most fluid, imagine holding a flat sheet at an angle and letting all the substances flow down the incline.
The substance which will reach down the fastest will be the most fluid and the slowest one will have the least fluidity.
Hence, in this case the order of fluidity is Water > Honey > Toothpaste .
