Correct answer: D. Honeybee , lac insect, cochineal insect
- A. Sandfly , butterfly, hoeybee
- B. Sikmoth, honeybee, locust
- C. Honeybee, silkmoth, tsetse fly
- D. Honeybee , lac insect, cochineal insect
Explanation
Honeybees provide honey and wax, lac insects provide lac, and cochineal insects provide the red dye carmine, making this the set of useful insects. Students may choose the silkmoth set, but locusts are crop pests and tsetse flies transmit disease, so those sets contain harmful insects.
