Correct option is B
According to Andrew Milner in "Re-Imagining Cultural Studies," of the four important kinds of meanings that Raymond Williams attaches to the word 'culture' in his early work, the three that remain in play in Keywords are:
(B) the state of intellectual development of a whole society
(C) the arts as a whole
(D) the way of life of a group or people
In Keywords, Williams identifies three broad categories of definition for "culture" in general usage
"a general process of intellectual, spiritual and aesthetic development"
"a particular way of life, whether of a people, a period, a group or humanity in general"
"the works and practices of intellectual and especially artistic activity"
These three definitions correspond to meanings (B), (C) and (D) respectively from Williams' early work. The search results do not mention Williams attaching an "individual habit of mind" as one of the four important meanings in his early work that remains in Keywords
Williams' definition of culture is broad and inclusive. He sees culture as encompassing all aspects of human life, from the intellectual to the artistic to the everyday. This definition has been highly influential in cultural studies, and it continues to be debated and discussed today. Milner argues that Williams' three remaining meanings of culture in Keywords are still relevant today because they offer a way to understand the complex relationship between culture and society. He writes that "Williams's meanings of culture are important because they allow us to think about the ways in which culture is both produced by and constitutive of society." Williams' work on culture is essential reading for anyone interested in understanding the field of cultural studies. His insights into the nature of culture and its relationship to society are as relevant today as they were when he wrote them.
