C. area
D. capable



Answer :

Let's analyze the definitions provided in the chart to determine the most likely definition of the root "fll."

1. Influx: This word is defined as "movement into an area." The key part of this definition is "movement."

2. Sent: This word is associated with "wastewater discharged into the environment." While "sent" itself does not directly pertain to the root "fll," the concept of movement or transfer of liquid is involved.

3. Reflux: This word is defined as "to return or flow back into something." Here, the crucial part is "flow back."

4. Fluid: This word is described as "capable of flowing or moving freely like water." The significant part of this definition is "flowing."

Considering these definitions, the words "influx," "reflux," and "fluid" all emphasize the concept of movement, specifically related to "flow."

- Influx: Movement or flow into an area.
- Reflux: Flowing back.
- Fluid: Capable of flowing freely.

The common thematic element across these words is the idea of "flow." Therefore, the most likely definition of the root "fll" is "flow."

## Conclusion:
The root "fll" most likely means:

- Flow

So among the options provided:
- flow
- water
- area
- capable

The correct choice is flow.
