Yes, the term "No Character Style" would be a lot better.

Yes, that is the purpose of that button. But "Set to Parent" does not exactly
describe, what this button does, see below.

You cannot have "Default Character Style" as parent, because it is not a style.

A character, which has no character style applied, uses the character related
settings of that paragraph, to which the character belongs. That is the reason,
why a paragraph style has the tabs "Font" and "Font Effects" at all.

The Writer Options are bound to the paragraph style "Default Paragraph Style".
When you change the font in the Writer Options it will change in the "Default
Paragraph Style" and vs.

Agree.

No. The list, which will contain "No Character Style", refers to the object,
which gets a style applied, or in this case, which gets the style erased. But
the "Inherit From" refers to the definition of a style itself. That are
different contexts.

> C. The "- None -" option should be removed from the 'Inherit From' choices

No. It indicates, that the style has no parent style. That option is available
for all styles, which allow a hierarchy, and has always the same meaning.

The button does in both cases the same. It removes the properties in that
dialog tab from the set of properties, which get a value by this style. The
result can be seen in the Organizer tab.

If a property has no value in the style, which is applied to an object, then
LibreOffice needs to get the value from somewhere else. The mechanism for that
is described in detail in the standard.

The problem is, to explain the inheritance mechanism to the user. And it is
obviously difficult to explain, why it is useful, that the character styles are
not inherit from a common root style, but the paragraph styles have a common
root style.
