Answer: C

Explanation:

To meet the Increased Ventilation strategy under the Enhanced Indoor Air Quality Strategies credit, the breathing zone outdoor air ventilation rates must be increased by at least 30% above the minimum rates required by ASHRAE 62.1-2010. This increase is intended to improve indoor air quality and promote a healthier indoor environment.

Reference: The LEED v4 reference guide for Interior Design and Construction includes this requirement as part of the strategies to enhance indoor air quality12.
