Final answer:
The feature that is not a basic part of a green column is the capital. A pendentive is not a basic part of a column structure in Classical architecture; it's a feature used to support a dome, unlike a capital, post, or entablature which are integral parts of a column.
Step-by-step explanation:
The feature that is not a basic part of a green column is the Capital. In the Classical orders of architecture, the capital is the decorated top of a column or pilaster. The other options - pendentive, post, and entablature - are elements that are associated with columns.

The feature that is not a basic part of a green column is option B) Pendentive. A green column, as used in Classical architecture, typically includes several components. Capital (option A) is the decorated top of a column. The entablature (option D) is the structure above the columns that supports the roof and includes a cornice, frieze, and architrave. A post (option C) is another term for a supporting column. However, a pendentive is an architectural element that allows for the placement of a circular dome over a square room or space; it is not a part of a column itself. Engaged columns are columns that are not freestanding but become part of the wall they support, including its entablature. The feature that is not a basic part of a green column is the Capital. In the Classical orders of architecture, the capital is the decorated top of a column or pilaster. The other options - pendentive, post, and entablature - are elements that are associated with columns.
