Answer: I would contend that the right answer is the A) Freedom to consume is equated with freedom itself.
Explanation: Just to elaborate a little on the answer, it can be added that in this excerpt from Susan Sontag's On Photography, it is possible to infer that the American author is critical of capitalist societies, since she is asserting that people in those societies (may) mistake their freedom to consume—images and goods—with freedom itself. In other words, the economic freedom that is characteristic of a capitalist society is mistakingly equated with political freedom.
The other three excerpts do not suggest that strongly her criticism of capitalist societies, since they do not contain any reference, specific or not, to capitalism.
