Final answer:
Stage clips are the components that secure the glass slide on the stage of the microscope, which helps in positioning the specimen and preventing contamination.
Step-by-step explanation:
The components that support and position the specimen and prevent contamination of the microscope by the specimen are c) Stage clips. Stage clips hold the glass slide in place on the stage, thereby ensuring that the specimen stays secure while being examined under the microscope. By keeping the slide from moving, stage clips help prevent potential contamination of the microscope's lenses or the stage itself. It is important to not allow lenses to contact the slide to avoid damage and contamination.
