Answer 1

Right answer is (c) Heart

Explanation: Beta blockers are Beta-adrenergic receptor blockers – they block the action of Adrenalin and Noradrenaline (SNS stimulants), which are involved in “Fight-or-flight’ response. There are two types of Beta receptors β1 – found mostly in the heart and β2 – found mostly in the lungs.
