Read the statements carefully and choose the correct option.
Statement I: Neutral molecules may pass through cell membrane by simple diffusion
Statement II: Polar molecules require carrier protein to pass through the cell membrane

Statement I is correct. Neutral solutes may move across the membrane by the process of simple diffusion along the concentration gradient, i.e., from higher concentration to the lower.

Statement II is also correct. The polar molecules cannot pass through the nonpolar lipid bilayer, they require a carrier protein of the membrane to facilitate their transport across the membrane.
