TheLEED for Homes Rating System (v4)addresses fireplaces in theIndoor Environmental Quality (EQ) Credit: Enhanced Combustion Venting, which promotes safe combustion practices to prevent indoor air quality issues from fireplaces.
According to theLEED Reference Guide for Homes Design and Construction (v4):
EQ Credit: Enhanced Combustion Venting (1 point)
For fireplaces, install doors and ensure they are direct-vented or power-vented to prevent combustion byproducts from entering the home. Unvented fireplaces or appliances are not permitted due to indoor air quality risks.

TheLEED v4.1 Residential BD+Crating system confirms:
EQ Credit: Enhanced Combustion Venting
Fireplaces must have doors and be vented to the outdoors (e.g., direct-vent) to qualify for the credit, ensuring safe operation and minimal indoor air pollution.

The correct answer isinstall doors on the fireplace(Option A), as this, combined with proper venting (assumed in LEED-compliant fireplaces), ensures safe operation and compliance with the credit.
Why not the other options?
