Answer: (B)

The color white in excavation marking typically signifies proposed excavation areas. This designation is crucial as it communicates to contractors, excavators, and inspectors that these marked locations are planned for excavation, allowing for appropriate safety measures and coordination among involved parties. When white marks are visible, they indicate that excavation work is anticipated, which serves to alert other stakeholders to potential interactions with underground utilities and existing structures during the planned work.
