Correct answer: D

Explanation

  1. Total in 2022: 120+80=200120 + 80 = 200. Total in 2025: 160+96=256160 + 96 = 256.

  2. Growth: 256−200=56256 - 200 = 56.

  3. Percentage growth: 56200×100=28%\frac{56}{200} \times 100 = 28\%.

Worth noting

21.9% divides the growth by the 2025 total instead of the 2022 total. 20% is the growth in Commerce alone. 26.7% averages the two streams' growth rates, which ignores that Science is the bigger stream.
