Answer:
The answer is the 4th one.
Explanation:
Observing the data, we can see a relationship between the amount of light exposure and the amount of bubbles (oxygen) produced in photosynthesis.
As the distance from the light source increases, we see the number of bubbles decrease. We can establish that semi-linear relationship, therefore eliminating option 2.
Option 3 is not directly related to the data in the table, but rather about the inner workings of photosynthesis.
That leaves us with option 1 and option 4. They are both correct, and can be interpreted from the data provided; however, option 1 is vague, and does not use specific data points, only a relationship derived from them.
Therefore, by elimination of options, we can clearly see the correct option is the 4th one.
