Answer:
a. Wolfe, Lin, and Critchlow
Step-by-step explanation:
We choose random sample of subjects based on the first random number from left to right and since 4(number appears two times so we wait for next different number) and 9 come first we choose Wolfe and critchlow. The third Subject as we have to choose 3 subjects per sample is Lin since her number 8 appears next. Also the order doesn't matter so we could have Wolfe, Lin, and Critchlow or Critchlow, Lin, Wolfe or in any other order
