Step 1: Idea:
We use the purpose of the chart and then check the options for contradictions.
Step 2: Use the purpose of a scatter plot.
It is made of dots, and it relates two numeric variables. Those two facts match (D) and (A).
Step 3: Rule out (B) and (C).
Categorical summaries come from bar charts. Part-of-whole proportions come from pie charts. So (B) and (C) are false.
Step 4: Match with the options.
Options 1, 2 and 3 each contain (B) or (C), so they are wrong. Option 4 has only (A) and (D).
Step 5: Test every option against the result.
Option 1: This set has (B), and (B) is false, so the set fails.
Option 2: This set has (B) and (C), and both are false, so the set fails.
Option 3: This set says all four are true, but two of them are false, so it fails.
Option 4: This set keeps only the two true statements (A) and (D), so it fits.
Step 6: Conclusion.
Option 4 is correct.
\[ \boxed{(A)\text{ and }(D)\text{ only}} \]
