To find the correct answer, we first need to determine how many students have completed their science projects.

Given that 80% of the 20 students have completed their projects, we can calculate the number of students who have completed their projects by multiplying 20 by 80% (or 0.80).

20 x 0.80 = 16

Therefore, 16 students have completed their science projects.

To find out how many students still need to finish their projects, we subtract the number of students who have completed their projects from the total number of students.

20 - 16 = 4

Therefore, 4 students still need to finish their science projects, which means the correct answer is D.

16
