Triple

Target class: bipolar limb lead
Context triple: [Lead I, instanceOf, bipolar limb lead]

• A. bilateral command
  A bilateral command is an instruction or directive that involves or requires coordinated action, agreement, or communication between two distinct parties or sides.
• B. bipolar junction transistor configuration
  A bipolar junction transistor configuration is a specific arrangement of a BJT’s terminals and external components (such as common-emitter, common-base, or common-collector) that determines its input-output relationships, gain characteristics, and typical application in electronic circuits.
• C. unipolar laser
  A unipolar laser is a semiconductor laser device that generates coherent light through electronic transitions within a single type of charge carrier band, typically using intersubband transitions in quantum wells rather than electron–hole recombination.
• D. paired artery
  A paired artery is one of a symmetrical set of two arteries that run on opposite sides of the body or an organ, typically supplying the same type of tissue or region.
• E. biological pacemaker
  A biological pacemaker is a living, cell-based or genetically engineered tissue system that generates and regulates rhythmic electrical impulses to control the heartbeat as a natural alternative to electronic pacemaker devices.
• F. None of above. chosen
