Hi!
The answer would be B. Positive
Explanation:
A positive feedback mechanism is that in which a stimulus induces an output which in turn functions to magnify the same response <em>(acting as a stimulus to itself). </em>
As in this case, Ethylene acts as a stimulus for fruit ripening (<u>response</u>). When it is released during fruit ripening, it stimulates nearby fruits to ripen (<u>response</u>), which in turn acts to stimulate further fruits to ripen (<u>response</u>), resulting in the effect being widespread (<u>magnified</u>)
Hope this helps!
