IV. Vallisneria, Chimpanzee, Red-eyed frog, Fern

• A. Vallisneria is wrongly placed in group IV and should be replaced with sea horse.
• B. In group I, toucan is placed incorrectly and should be replaced with kangaroo rat.
• C. Lion-tailed macaque is incorrectly mentioned in group II and should be included in group I.
• D. In group III, sea horse is placed incorrectly and should be replaced with Ceratophyllum.

Answer 1

The correct option is B

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.
