A) Elephant	B) Giraffe
C) Lion	D) Rabbit

Answer & Explanation Answer: B) Giraffe

Explanation:

Giraffe has the highest blood pressure among animals.

This is due to the fact that there is a large pressure drop (~100 mmhg) as the blood is transported from the heart, up the neck, to the brain. This is about twice the normal blood pressure of humans (120/80 mmhg).
