(a) none
(b) one
(c) two
(d) four
Please help with this..

Dear student,
Please find below the answer:

The correct option is (b).
The number of nuclei present in a zygote is one. The zygote is formed by the fusion of the two nuclei from the parents. So, it is two nuclei fused into one. 

Hope this clears your doubt.
Regards.
