Answer: First option is correct.
Explanation:
Since measurements, observations, and data can be displayed on a graph, whereas predictions can not be displayed on a graph.
When we have the collected data, we can display with the help of graph.
When we have observations, we can display it too.
When we have measurements, we can also display it.
All those things which are in numerical terms, we can display it on the graph.
But prediction is just an assumptions that an individual is supposing to occur, so it may be not in numerical terms.
Hence, First option is correct.
