Final answer:
Glass ionomer cement (D) is the type I dental cement that acts as an adhesive for indirect restorations and tooth structure.
Step-by-step explanation:
A dental cement that is classified as type I and functions as an adhesive to secure indirect restorations such as crowns, bridges, and inlays to the tooth structure is known as glass ionomer cement (D). This material forms a chemical bond with the tooth structure and can release fluoride, which may help to prevent further decay. In contrast, zinc phosphate cement (A) was traditionally used but is less common now, dental amalgam (B) is a filling material not typically used as a cement, and composite resin (C) is also used for fillings and as a restorative material but does not fit the description of type I cement.
