Both statements are correct.

Statement (I): Adsorption chromatography is indeed based on the principle that different compounds are adsorbed on an adsorbent to different degrees. This is due to the fact that different compounds have different affinities for the adsorbent, which allows for the separation of the compounds as they move through the adsorbent at different rates.

Statement (II): Silica gel and alumina are commonly used as adsorbents in thin layer chromatography. These substances are used because they have a high surface area, which allows for a greater amount of adsorption to occur. Additionally, they have different affinities for different compounds, which allows for the separation of the compounds in a mixture.
