Explanation:

Option 1 is incorrect because of the word planned. The passage states, “…many of the concepts of modern art, by contrast, have resulted from the almost accidental meetings of groups of talented individuals at certain times and certain places. The ideas generated by these chance meetings…”.
Neither option 2 nor 4 have been mentioned in the passage.
Option 5 contradicts the passage. The passage states, “A scientific discipline develops systematically once its bare tenets have been established, named and categorized as conventions. Many of the concepts of modern art, by contrast, have resulted from the almost accidental meeting of groups of talented individuals at certain times and certain places.” This implies that the concepts of modern art have not been the product of systematic conventions. Moreover the following extract , “Certainly one can understand that artists are wary of being pigeon-holed” as well as “There is good reason to accept the ideas codified by artists and critics, over the past sixty years or so, as having attained the status of independent existence” indicates that the concepts of modern art have not been the product of codification.
Option 3 is explicitly mentioned in the passage, “…many of the concepts of modern art, by contrast, have resulted from the almost accidental meetings of groups of talented individuals at certain times and certain places. The ideas generated by these chance meetings…”
Hence, the correct answer is option 3.
