Safety Data Sheets (SDS) differ from Material Safety Data Sheets (MSDS) primarily in their standardized format, and the correct answer highlights that SDSs are structured according to a standardized 16-section format known as the Globally Harmonized System (GHS). This system was designed to enhance safety for users by providing clear and consistent information regarding the properties of chemicals, hazards, and safe handling practices.

The GHS format enables easier understanding and communication of hazards across different countries and industries. Each section of an SDS provides vital detail, such as composition, exposure controls, safety measures, and toxicological information, allowing users to handle chemicals more safely and effectively in a variety of settings. By having this consistent structure, it not only improves safety but also facilitates compliance with regulatory requirements across various jurisdictions.

While there may be differences in purpose and detail between SDSs and MSDSs, the key distinguishing factor lies specifically in the standardized format used in SDSs, making option D the most accurate and relevant answer.
