Ummm.... Okay, what is happening to the distance from O as you walk across the diameter?O.K. I see that 4 isn't correct. Can you give me more clues?
Please answer my question.
What is the distance from A when time=0 ? Whatpoint on the graph does this
The distance decreased so the answer is (2). IN the beginning the distence is radius and its becomes 0 in the half of diameter.Ummm.... Okay, what is happening to the distance from O as you walk across the diameter?
What is the distance from O as you walk around the semicircle?
C'mon! You are missing the obvious here.

Thanks.
None of the graphs is correct, if you translated the problem correctly.Wiki go from "point A" by doing fast walking on a road that its' shape is semi-circle, that O is its center. What is the graph that presents the distance from point A when she go from A and back?

y-axis is presenting the distance from O
x-axis is presenting the time.
I believe you are saying that this is the correct translation of the problem:The graph is the Distance from the current location of her to O. I miss the part of the question. Do you want me to rewrite the question again?
Notice: I write after graphs the meaning of the axis that can tell you what the orginal question is about?
I write a mistake. I meant to [say] graph 1.
This is correct, now that we know the actual problem. Please be more careful in the future.The distance is R at the beginning. Am I right?
Someone probably should have pointed out that inconsistency to you.y-axis is presenting the distance from O
x-axis is presenting the time.
