When ventricles contract, blood is pumped... a. into the veins
b. out of the heart
c. into the heart​

C.) Into the heart

Once the ventricles flow through veins, the blood goes to the heart, it literally goes to the heart so the heart can pump the blood to your veins and it flows throughout your body.

Hope this help. :)
