A "stabilizer" is a common term used to refer to fixative, especially in photography. The function of a stabilizer is to stop the development process and preserve the desired image on photographic paper. This is why the other options are incorrect. "Thio" is not a commonly used term in photography and does not describe the function of a stabilizer. "Caustic" typically refers to something that is able to burn or corrode and is not related to photography. "Ammonium" is a type of chemical compound and does not describe the function of a stabilizer. Therefore, the correct and most specific term for a stabilizer in the context of photography is "fixative."
