Choose correct statement about Electrocardiogram Augmented Limb Leads.

a. In this type of limb lead system, two of the limbs are connected through the positive terminal of the electrocardiograph, and the third limb is connected to the negative terminal. 

b. In this type of limb lead system, two of the limbs are connected through the negative terminal of the electrocardiograph, and the third limb is connected to the positive terminal. 

c. When the positive terminal is on the right arm, the lead is known as the aVR lead; when on the left arm, it is known as the aVL lead; and when on the left leg, it is known as the aVF lead.

d. When the negative terminal is on the right arm, the lead is known as the aVR lead; when on the left arm, it is known as the aVL lead; and when on the left leg, it is known as the aVF lead.
