Saurabh classified living organisms in four groups (I, II, III and IV) each containing four members based on the habitats in which they are found. In doing so he unknowingly placed one wrong member in each group. Identify the odd one out and select the correct option regarding this.
I. Acacia, Camel, Toucan, Aloe
II. Penguin, Fur seal, Polar bear, Lion-tailed macaque
III. Sea horse, Octopus, Corals, Silverfish
IV. Vallisneria, Chimpanzee, Red-eyed frog, Fern
In group I, toucan is placed incorrectly and should be replaced with kangaroo rat.
The odd one out in first group is toucan which is adapted to rainforests unlike other three which are adapted to deserts.
Lion-tailed macaques from group two are residents of rainforests and other three are adapted to mountainous regions.
Silverfish from group three are residents of rainforest and other three are adapted to aquatic habitat.
Vallisneria being an aquatic plant is odd one out and the other three are adapted to rainforests.
