Answer 1

The answer is Anscombes quartet.

Explanation: The question itself is asking about an example so the option a and c can be neglected as they are concepts.

About the option d, I dosent found interesting in the pattern of the napoleans March.

And about the answer,

Anscombe's quartet comprises four data sets that have nearly identical simple descriptive statistics, yet have very different distributions and appear very different when graphed. Each dataset consists of eleven (x,y) points. They were constructed in 1973 by the statistician Francis Anscombe to demonstrate both the importance of graphing data before analyzing it and the effect of outliers and other influential observations on statistical properties. He described the article as being intended to counter the impression among statisticians that "numerical calculations are exact, but graphs are rough."

Just look at those 4 data sets .Which seems to be simple and have lots of similarity. It looks like identical with simple summary statistics. But when we plot it , can see the wonder, how different it was .
