Given below are two statements: Statement (I): Transportation in organisms and animals occurs by diffusion and by passive transport between the cells. Statement (II): This mechanism is suitable where the surface area of body is large and the distance between parts of the body in the organism is small. In light of the above statements, choose the most appropriate answer from the options given below.

Step-by-step solution

Statement (I) is incorrect because in complex organisms and higher animals, transportation of substances over long distances cannot rely solely on diffusion and passive transport, as these processes are too slow. Instead, they require specialized circulatory systems for bulk flow. Statement (II) is correct because diffusion and passive transport are only effective and suitable for organisms where the surface area to volume ratio is large and the distance between different parts of the body is very small (e.g., in s
