      A By planting non-Bt crops in the entire field Correct Answer Incorrect Answer
      B By using higher doses of Bt cotton seeds Correct Answer Incorrect Answer
      C By ensuring all insects in the field are Bt-resistant Correct Answer Incorrect Answer
      D By allowing mating between susceptible insects from non-Bt crops and resistant insects from Bt cotton Correct Answer Incorrect Answer

      Solution

      Explanation: The Refugia Technique prevents resistance development by allowing mating between susceptible insects from non-Bt crops and resistant insects from Bt cotton. In the next generation (F1), the progeny obtained is susceptible to Bt, as the recessive gene doesn't express itself in F1 generations.
