C: Branch of circumflex aery
Answer: C: Branch of circumflex aery 
Explanation: Kugel's aery - come from proximal circumflex aery & reach distal pa of right coronary aery (have variations) - help in emergencies AERIAL SUPPLY OF HEA:- There are left & right coronary aeries which are coming from ascending aoa.- Ascending aoa have 3 coronary sinuses- Right coronary aery - from right coronary sinus of ascending aoa- Left coronary aery - from left coronary sinus - Left coronary aery divides into * Left anterior descending aery/ Anterior Inter-ventricular aery running on & supplying anterior interventricular septum- Circumflex aery (around & behind hea) which anastomose with right coronary aery.- Though, they do have anastomosis anatomically, physiologically they are not going to help each other.- Kugel's aery - come from proximal circumflex aery & reach distal pa of right coronary aery (have variations) - help in emergencies * Some times; connected to coronary venous sinus of hea forming aeriovenous anastomosis
