The answer is B.
Step-by-step explanation:
We want 1/6 of 144, so we divide 144/6=24 students.
Then, only 2/3 of those 24 students will make it to the final round. So, we want to know how many students are in three (2/<u>3</u>) groups and we want two (<u>2</u>/3) of those groups. So, we divide those 24 students by 3 to know each group has 8 students and then we want 2 of those groups (remember <u>2</u>/3), so we multiply 2x8=16 students in the final round.
