a. nonmaterial culture.
c. language.
b. material culture.
d. values

The correct answer is - b. material culture.

The material culture is a set of physical objects of all sorts, that have been created by a particular group of people that share the same culture. This part of the culture, the material one, is often the one that most people pay attention to, and that is because it is the visible part of someone's culture. Also, the material culture has a crucial importance in the archaeology, as the physical objects are the ones that testify about the cultures of the past, or the evolution of the cultures that we now have.
