43% of the students prefer biology
Step-by-step explanation:
Among girls:
39 of the students are girls.
21 of the girls like biology best.
Boys:
100 - 39 = 61 are boys.

11 out of the 34 who prefer chemistry are girls, so 34 - 11 = 23 are boys.
61 - (16 + 23) = 22 prefer biology.

43% of the students prefer biology
