Which project type earns a single point under the Light Pollution Reduction credit?

The correct choice reflects that all project types are eligible to earn a single point under the Light Pollution Reduction credit in the LEED BD+C V4 framework. This credit is designed to promote responsible lighting design to reduce light pollution, which has benefits for both the environment and human health.

The requirements for this credit apply universally across various project types, recognizing that light pollution can affect any building, regardless of its function or use. Consequently, all projects can implement strategies to minimize light trespass, mitigate glare, and promote glare-free exterior lighting that complies with the credit's criteria, thereby earning the point specified under the credit requirements.

In contrast, the other options, like healthcare facilities, schools, or core and shell projects, could imply that only specific projects can achieve this point, which is not the case. Since the Light Pollution Reduction credit is universally applicable, the answer indicating that "all projects" can earn the point is the most accurate representation of the credit's intent.
