Novice bird-watcher: I don’t know much about animal track’s, but I do know that birds typically have four toes, and most birds have three toes pointing forward and one toe pointing backward. Since this track was made by an animal with four toes of which three point forward and one points backward, we can conclude it was made by some kind of bird.

The argument is flawed because it

(A) relies on the vagueness of the term “track”
(B) does not define birds as animals with four toes
(C) fails to identify what kind of bird might have made the track
(D) does not establish that only a bird could have made the track
(E) depends on evidence about an individual bird rather than about birds in general

hello expert,

if option d is correct, why we want to establish that "only a bird has made the track "?

We don't want to establish that. there can be more than one way of making tracks like that perhaps by different animals,insects(just saying)
This is an example of a classic flaw question.
Whenever there is an argument which shows that there is only one way of dung something ,the correct flaw answer will be to find an option that shatters that assumption.

Out of scope.
(B) does not define birds as animals with four toes
Not the main flaw.
(C) fails to identify what kind of bird might have made the track
type of bird is out of scope.
(D) does not establish that only a bird could have made the track
Any other animal could have made the track as the argument fails to specify that only birds have four toes.
(E) depends on evidence about an individual bird rather than about birds in general
out of scope.
