Select the most appropriate option to fill in blank number 1.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. rich.
Context: The sentence says power foods provide a lot of nutrients like fibre, potassium, and minerals. So we need a word that means "a high amount" of something.
Meaning of "rich": "Rich" means full of or high in something useful or important.
For example, “Spinach is rich in iron” means spinach has a lot of iron.
Why "rich" fits: "Rich levels of nutrients" means the food has plenty of nutrients, which matches the idea of power foods.
Hence, the chosen option will be correct.
