What type of knowledge pertains to understanding the features of an object, such as the properties of rocks?

The correct answer focuses on physical knowledge, which involves understanding the tangible attributes of objects, including their properties and characteristics. In the context of rocks, physical knowledge would include aspects such as hardness, texture, color, and composition. This type of knowledge is empirical in nature, derived from observation, measurement, and interaction with the physical world.

Domain knowledge, while related, is broader and refers to expertise in a specific field or subject area, which in this case would encompass more than just the physical properties of rocks. Syntactic clues are related to the patterns and structures found in language rather than physical objects. Empirical knowledge, although linked to observations and experiences, is a more general term that encompasses all knowledge gained through experience rather than focusing specifically on the physical attributes of objects.
