The design of a space that is intended to be experienced as art is called
o
a. an installation
o
b. an interactive blog
o
c. a performance
d. a poetry reading

The answer is A.

Explanation:

Since we're dealing with design of a space it is clear we're not talking about traditional arts (such as theater, writing, sculpture, architecture...) but about contemporary arts. Now let's analyze the answers.interactive blog is an informal website created and run by an individual who shares his opinions and content with the visitors. Poetry reading is public recitation of poetry. With these two answers excluded let`s talk about the other two. Both installation and performance, are types of contemporary art. In the performance, artist's action and interactions with other object play the main role, while as in the installation, the message is conveyed through a particular 3D object placed inside a specifically designed space ( a corner, a room, a warehouse, old abandoned building).

hm, switch the relative; nominative and indefinite; objective ? not too bright in the knowledge of the english.
