The answer must be (E).

"such as" in (A) would be appropriate if it were linking noun phrases, but here it's modifying a clause and introducing a clause.

(B) is unnecessarily wordy.

In (C) and (D), the underlined portion is imposing conditions or limitations on when television is superficial -- specifying the conditions under which it is superficial.

(E) uses the right modifier to give an example of when television is superficial. (A), though badly worded, was clearly an attempt to give an example, not set conditions, so that's the right reading -- and in any case (D) would be a bit silly, because it's very unlikely that the writer would've wanted to say that television is superficial only if this one specific thing happens.
