Question

Consider the following statements:

1. Some species of turtle are herbivores

2. Some species of fish are herbivores

3. Some species of marine mammals are herbivores

4. Some species of snakes are viviparous 

Which of the statement given above are correct?

(a) 1 and 3 only

(b) 2, 3 and 4 only

(c) 2 and 4 only

(d) 1, 2, 3 and 4

Answer 1

Correct option is (d) 1, 2, 3 and 4

Cobras, the pythons, the keelbacks don't lay eggs so they're called 'viviparous' as bring out live young. So, #4 is right. Answer could be b, c or d, in all these options, #2 is common so we've to accept 'Some species of fish are herbivores' are true without verification.

Depending on the species, sea turtles may be carnivorous (meat eating), herbivorous (plant eating), or omnivorous (eating both meat and plants). So #1 is right and by elimination we are left with answer d: all statements are correct.
