You're safe in a boat. A swarm of sharks comes while your parents are swimming. Would you save your mom or dad?

It's the morning, the sun has penetrated through the clouds and is gleaming on the water reflecting your inner most desires. Your parents decided to go for a swim in the ocean. A swarm of sharks detects the blood that has diffused in the water from your father's cut on his ankle. A frenzy of sharks starts swarming and prepares to strike its prey. If you could only save ONE, who would you save? Mommy? Dadio?
