Koun Banega Karodpati question

 I came across this question on Koun Banega Karodpati program recently.

Question 

Which bird is capable of killing humans with a blow of its feet ?

1.  Penguin

2.  Asbestos 

3.  Cassowary 

4.  Sea Gul 

Answer 

After reading the options, Sea Gul is a bird which I have seen always flying and I heard that sometimes sailors hunt and eat this bird to quench their hunger. 

Asbestos is a migratory bird known for its longest flying ability.

Penguin is a huge flight less bird but I never heard that it has killed someone with a blow of feet. 

We are now left with cassowary bird which is a flight less bird.

It is big in size and using its powerful feet, it can kill humans with a blow.

Same thing with ostrich.  But ostrich don't get aggressive easily.
