With reference to the physiological adaptations of mangrove plants in India, consider the following statements: 1. Vivipary is an adaptation where seeds germinate while still attached to the parent tree, preventing them from being swept away or suffocated in anaerobic saline mud. 2. Pneumatophores contain specialized pores called lenticels that facilitate oxygen uptake in waterlogged, oxygen-depleted soils. 3. Species of the genus Avicennia exhibit cryptovivipary, where the embryo emerges from the seed coat but remains hidden inside the fruit before falling. Which of the statements given above are correct?

Options:

• A: 1, 2 and 3
• B: 1 and 2 only
• C: 2 and 3 only
