The passage given below is followed by four summaries. Choose the option that best captures the author’s position.

The conceptualization of landscape as a geometric object first occurred in Europe and is historically related to the European conceptualization of the organism, particularly the human body, as a geometric object with parts having a rational, three-dimensional organization and integration. The European idea of landscape appeared before the science of landscape emerged, and it is no coincidence that Renaissance artists such as Leonardo da Vinci, who studied the structure of the human body, also facilitated an understanding of the structure of landscape. Landscape which had been a subordinate background to religious or historical narratives, became an independent genre or subject of art by the end of sixteenth century or the beginning of the seventeenth century.

Let us note down the main points of the given paragraph:

The given paragraph describes how the study of landscape gained prominence and became an independent genre. Renaissance artists facilitated the development of the field as an independent genre. 

Let us evaluate the options one by one.

Option A states that understanding of the organism in Europe led to a similar approach towards the understanding of landscape. Though this option is true, it fails to capture the fact that the field evolved as an independent genre with the help of Renaissance artists. 

Option B states that Landscape became a major subject of art at the turn of the sixteenth century. Again, option B fails to capture the role played by the Renaissance artists. 

Option D states that Renaissance artists were responsible for the study of landscape as a subject of art. The paragraph mentions that the artists facilitated in the transformation of the field into an independent genre. Option D establishes a strong relationship and holds Renaissance artists 'responsible' for the study of landscape 'as a subject of art'. The parts within the quotes disregard the fact that the artists just aided the process. They were not solely responsible for the development. Therefore, we can eliminate option D. 

Only option C captures the fact that the renaissance artists 'aided' in the development of the study of landscape as an independent genre and hence, option C is the right answer.
