The Following Excerpt Is a Portion of a Patient's Emergency

The following excerpt is a portion of a patient's Emergency Department Course. The team found that she was bleeding in her bronchi and treated her with endobronchial electrocautery. Afterward, she was transferred to the ICU for further care.
The patient was treated with endobronchial electrocautery. What is the correct breakdown and translation of this term?

A) endo (outside) + bronchi (bronchus) + al (pertaining to) + electro (electricity) +cauter (burn) + y (procedure) = cauterization of the outside of a bronchus using an electric current
B) endo (around) + bronchi (bronchus) + al (pertaining to) + electro (electricity) +cauter (burn) + y (procedure) = cauterization around a bronchus using an electric current
C) endo (inside) + bronchi (bronchiole) + al (pertaining to) + electro (electricity) +cauter (burn) + y (procedure) = cauterization of the inside of a bronchiole using an electric current
D) endo (inside) + bronchi (bronchus) + al (pertaining to) + electro (electricity) +cauter (burn) + y (procedure) = cauterization of the inside of a bronchus using an electric current
E) endo (outside) + bronchi (bronchiole) + al (pertaining to) + electro (electricity) +cauter (burn) + y (procedure) = cauterization of the outside of a bronchiole using an electric current
