Answer:

The lead whose positive electrode is placed on the left leg is II or DII (option C).

Explanation:

The electrocardiogram or EKG is a method of recording the electrical activity of the heart, useful for the diagnosis of diseases related to rhythm and heart rate. The 12-lead EKG is commonly used.

The electrode located on the left leg corresponds to the positive pole of the II or D-II lead, a bipolar peripheral lead whose negative pole is on the right arm. The electrode on the left leg is also the positive pole of the D-III lead, which goes to the left arm, and of the monopolar AVF lead.

The other options are not possible because:

<em>AVR and AVL are monopolar leads located in the right and left arms, respectively.</em>

<em>I or D-I corresponds to the bipolar lead whose poles are located between both upper extremities.</em>
