Final answer:
The action described in the question is that of splattering bullet holes. From the given options, the best word that describes this action is 'D. Dispersing'.
Step-by-step explanation:
The term splattering, often associated with splattering of bullet holes, can be best described by option D, Dispersing. To splatter means to scatter or dash in small droplets or particles. The two descriptive sentences provided give us a sense of this: 'The rain danced on the pavement, sparkling droplets falling from cotton balls above' indicates a gentle, spread out form of liquid falling, akin to a fine mist or sprinkle. On the other hand, 'The rain pounded the pavement, pouring buckets from thundering gray clouds above' suggests a more intense, concentrated form of liquid falling, similar to clumping or clustering rather than splattering.When relating this to the images described, the second picture depicting red dots on a dark background dispersed everywhere with four spots of heavily concentrated regions aligns well with the concept of splattering. This image reflects a pattern of distribution analogous to bullet holes, which may spread out randomly and unevenly, some areas denser than others, thereby dispersing.
