The question asks about the mode of reproduction exhibited by mangroves. We need to identify the specific reproductive strategy that allows mangroves to thrive in their unique, often harsh, intertidal environments.
A) Viviparity — Mangroves are well-known for their viviparous reproduction. The seeds germinate and grow into a propagule (a young plant or seedling) while still attached to the parent tree. This propagule then detaches and floats away, often rooting quickly upon finding suitable substrate, thus increasing its chances of survival in the challenging intertidal zone.
The question asks to identify the oldest man-made lake in India, specifically located in Gujarat. This requires knowledge of ancient Indian history and geography related to water bodies.

Its construction dates back to the Mauryan period, specifically during the reign of Chandragupta Maurya, and was further improved by subsequent rulers like Ashoka and the Shaka ruler Rudradaman I. Inscriptions on the Junagadh rock provide detailed accounts of its construction and repairs, confirming its ancient origins and artificial nature.
