Solution

The correct option is D 1 mm per second
Most ciliates like the paramecium are wonderful swimmers. Their speed of motion is about four times their own length per second. Some species are so fast that you must add a thickening agent to the water to slow the organism down enough to study it.
Therefore correct option is D.
