Which of the following is NOT a basic feature of 'Art'?

Systematised body of knowledge is a basic feature of science.

The basic features of an art are as follows:

(i) Existence of theoretical knowledge: Art presupposes the existence of certain theoretical knowledge. Experts in their respective areas have derived certain basic principles which are applicable to a particular form of art. For example, literature on dancing, public speaking, acting or music is widely recognised.

(ii) Personalised application: The use of this basic knowledge varies from individual to individual. Art, therefore, is a very personalised concept. For example, two dancers, two speakers, two actors, or two writers will always differ in demonstrating their art.

(iii) Based on practice and creativity: All art is practical. Art involves the creative practice of existing theoretical knowledge. We know that all music is based on seven basic notes. However, what makes the composition of a musician unique or different is his use of these notes in a creative manner that is entirely his own interpretation.
