解析：这道题考察的是词语的用法和区别。在英语中，supplemental和supplementary都是形容词，意思是“补充的”，但是它们在使用上有一些区别。supplemental通常指的是在原有基础上额外提供的信息，起到弥补不足的作用；而supplementary则更强调是在原有信息的基础上进一步扩展或完善。在这道题中，正确的答案是A，因为这份文件提供的信息是对适用手册的补充，起到弥补不足的作用。
举个生动的例子来帮助理解：就好比你在学习数学的时候，老师讲解完一个定理后，给你发了一份额外的练习题，这份练习题就是supplemental information，是为了帮助你更好地理解和掌握这个定理；而如果老师给你发了一份关于定理背景知识的详细解释，那就是supplementary information，是为了让你对这个定理有更全面的了解。
