The author hypothesizes that Han purple was probably discovered by accident during the production of glass. This is based on the fact that the same chemical ingredients are used for Han purple and a common type of white glass that was made during the period Han purple was made. In addition, both Han purple and this white glass were made using processes that involved high heat and mixing in lead.

The author assumes there’s no more likely explanation for the origin of Han purple besides accidental discovery during the production of white glass.

This strengthens by establishing at least that Han purple and white glass were produced near each other. If this were not true, the author’s hypothesis wouldn’t make sense. (A) isn’t a powerful strengthener, but it most strengthens compared to the other answers.

The purposes of Han purple and white glass doesn’t reveal anything about how Han purple was discovered.

This limits the number of people who knew how to make Han purple. But does this help show that Han purple was discovered during the production of white glass? We have no reason to think so.

How easy the ingredients were to obtain doesn’t shed any light on whether Han purple was discovered during the production of white glass.

(E) suggests white glass might have been more widely used or more durable. But that doesn’t tell us anything about whether Han purple was discovered during the production of white glass.
