Only A are correct. A, B, and Care correct.
Solution
The third option is correct. Water is a good source for pollination or spreading of gametes.
The option D is correct. Angiosperms are evolved advanced and have various types of
pollination system. This helps the greater availability of them.
The option C is correct. Insects have advance type of tracheal based respiratory system.
The option D is correct. Radula is a hard anatomical structure used for feeding by scraping or
cutting food. This is characteristic of Mollusca phylum.
The option A is correct. Lungs are importantly developed in reptiles to live in land.
The option D is correct. Hydrozoa a class of Cnidaria are always polyp..
