Not attemptedCorrect Answer: (b) Only 2
Spirogyra is a filamentous green alga found exclusively in freshwater habitats, so it is not common to both ponds and oceans, making statement 1 incorrect. Chameleons can move their two eyes independently and view different directions simultaneously, so statement 2 is correct; therefore only statement 2 is right.
