\newline

Choose

1

answer:

\newline

(A) Ask

200

residents of her district whose names are chosen at random.

\newline

(B) Ask

200

parents at the local playground.

Represent Entire District: To make a valid conclusion, the survey must represent the entire district population, not just a specific group.
Random Selection: Option (A) involves selecting $200$ residents at random, which is likely to provide a more representative sample of the entire district.
Biased Sample: Option (B) involves asking $200$ parents at the local playground, which could be biased as it does not represent the entire district population.
Choose Random Residents: Therefore, the best method for Councilwoman Kelly to get a valid conclusion is to choose a random sample of residents from her district.
