TheLEED for Homes Rating System (v4)includes theSustainable Sites (SS) Prerequisite: No Invasive Plants, which ensures that landscaping does not introduce invasive species that could harm local ecosystems.
According to theLEED Reference Guide for Homes Design and Construction (v4):
SS Prerequisite: No Invasive Plants
All site vegetation must be non-invasive, as verified by the USDA Cooperative Extension Service or an equivalent authority (e.g., local native plant societies or university extension programs). Invasive species are those that are non-native and likely to cause environmental harm.

TheLEED v4.1 Residential BD+Crating system confirms:
SS Prerequisite: No Invasive Plants
All plants must be verified as non-invasive by the USDA Cooperative Extension Service or equivalent to ensure they do not disrupt local ecosystems.

The correct answer isbe listed by USDA Cooperative Extension Service or equivalent(Option C), as this ensures that all site vegetation is non-invasive, meeting the prerequisite.
Why not the other options?
