You will be given a definition of a task first, then some input of the task.
In this task, you are given a context and four options. Each option is a suggested ending for the context. You should read the context and pick the best ending for the context. Please answer with "A", "B", "C", and "D".

[header] How to dissolve salt in water [title] Choose a salt. [step] There are many different salts available, and they all have different properties. The amount of epsom salt (mgso) that you can dissolve into a given amount of water at a given temperature will differ from the amount of table salt (nacl) that you can dissolve into the same water. <sep> (A) [substeps] They are either very high or very low salt. If you want a higher, more valuable salt, opt for some which will replace or exceed the normal low salt content. (B) The coating of salt is usually smaller but in density, and ranges in mass. [substeps] Mgsos are the spiralizers used to dissolve salt, but they do not harden as readily. (C) [substeps] You can find sea salt at marine supply stores, farmer's markets, or health food stores. Salt behaves differently in different levels of water than table salt. (D) [substeps] If you are trying to understand the dissolution process in general, you should stick with using table salt since the particles are smaller and will therefore dissolve easier. If you need to study the properties of a specific salt, use that salt.
Output:
D
