- Correct answerBIf both assertion and reason are true but reason is not the correct explanation of assertion
- CIf assertion is true but reason is false
- DIf both assertion and reason are false.
Solution
Queen is the only fertile female in beehive, having immensely developed ovaries. She lives for several successive years laying about 2000 or more eggs a day and upto about 1,500000 eggs during her life time. The queen has a remarkable capacity of controlling the fertilization of its eggs. A fertilized egg is laid in a worker or queen cell or honey comb, while an unfertilized egg in a drone cell, the latter develops parthogenetically. The queen mates only once in a life time. The sperms stored in her spermatheca fertilize her eggs as long as she lives.
Hence, the correct answer is option: 'B'.
