Answer: It would be A

Step-by-step explanation:

First: Find Median

18,19,|19|,20,|20,20|,21,|22|,22,26

there is 10 numbers so it would be between 20 and 20. Add 20 and 20 and you will get 40 and divide by 2 to get 20. Your median is 20 and the dot should be on top of the 20.
Second: Find Quartile 1 and 3

Since it’s 5 numbers on each side, the math is friendly. So you count the first 2, then circle the next number and count the last 2. The one you circled is your Quartile 1 and do the same for Quartile 3. Q1 should be 19 and Q3 should be 22. Check if they are underneath that number you got.

Last: now you know that you just have to find the median and the Q1 and Q3 and you should get the answer which is A.
