Answer 1

Please help!

Answer 2

You know 3 of these answers are obviously nonsense.
Give it a try, which one is definitely not the answer at all?

Answer 3

Is it C?

Answer 4

You think C is definitely NOT the answer?

Answer 5

No, I think C IS the answer.

Answer 6

Alright :)
But the real goal of this question is to know why are A, B and D not the answer.
Do you know why?

Answer 7

Yeah (:
Is C the answer?

Answer 8

Perhaps, can you explain why you think C is the answer?

Answer 9

Because, the white blood cells fight off pathogens, and it will kill off the infection (:

Answer 10

Yea you could say it that way.

The way I would say it:
A can't be the answer because the respiratory system involves the lungs. The question doesn't say anything about the location of the parasite.
B can't be the answer because insulin is a protein that lowers the blood sugar level, it doesn't fight parasites.
And D can't be the answer because you don't want the parasite transported to the stomach, you want to kill it :)
