Final Answer :
B
Explanation :
The size of the organism has the largest impact on whether diffusion alone will move nutrients within it. This is because diffusion is an effective means of nutrient and waste transport only over small distances. In larger organisms, diffusion alone is too slow to transport substances efficiently across the entire body, necessitating specialized circulatory systems.
