Final answer:
The characteristic most common to all sculptures is that they exist in three-dimensional space. While sculptures can have a variety of intended lifespans, materials, and purposes, their distinction from two-dimensional art comes from their occupation of space with depth, in addition to height and width. Option A is correct.
Step-by-step explanation:
The question "All sculptors have this characteristic in common" can be explored by examining the inherent qualities of sculptures. While sculptures may share several attributes, they are inherently three-dimensional as they occupy space with height, width, and depth. Sculptures serve various purposes, including religious, cultural, or aesthetic, and they are constructed using a plethora of materials like metal, stone, or terracotta, each selected based on the artist's intent, available technology, and environmental considerations.
It is incorrect to claim that all sculptures are meant to last many years or are created solely for beauty, as some may be temporary or serve practical functions. The essential commonality is their three-dimensionality. Therefore, the most accurate statement is: A) They exist in 3-dimensional space.
Sculptures exhibit diversity in materials used, reasons for their creation, and their intended permanence, reflecting the variety present in sculptural art. This common characteristic of existing in three dimensions is what distinguishes them fundamentally from two-dimensional forms of art such as drawings and paintings.
