Solution
The correct option is A Five
- Double fertilisation is an event unique to angiosperms.
- It involves the fusion of one male gamete (haploid) with egg (haploid) to form zygote (diploid) that gives rise to an embryo.
- It is accompanied with fusion of other male gamete (haploid) with two polar nuclei (secondary nucleus) to form the primary endosperm nucleus (PEN) which gives rise to a nutritive tissue called endosperm.
- Hence, total of 5 haploid nuclei are involved in double fertilisation process.
- The correct answer is 'Five'.
