The correct answer is option c) unrestricted.

In line 49, “open” most nearly means unrestricted.

Option C is the right answer since the supplied sentence states, “Can a person’s uniqueness, dignity, and identity be separated from genetic difference and belief in a person’s limitless futures?”

Because the future is unpredictable and indeterminate, it is “open” because no one knows what will happen in the future. So “open” here nearly implies “unrestricted.”

Other choices include: Option A signifies clear or straightforward, as we all want our future to be clear. Option B indicates friendly, therefore consider how the future relates to the word friendly.

Option D indicates “not covered, not safe,” hence the statement does not fit with the term. Option E denotes that everyone knew or that everyone had rights.
