Did you see the question? Ask the difference between before and after. I think the correct answer is A, because the devdocs say …. after or before Specifies the element’s position relative to siblings. Use dash (-) to position the block before or after all other siblings of its level of nesting. If the attribute is omitted, the element is placed after all siblings. And they actually perform the same function.
Correct answer : C
Answer: C
before and after attributes
To help you to position elements in a specific order suitable for design, SEO, usability, or other requirements, Magento software provides the before and after layout attributes. These optional attributes can be used in layout XML files to control the order of elements in their common parent.

Definitley C as you can’t change a parent with a before and after only an elements position within a parent
I think the ans is C, the before and after only used in instruction not in referenceContainer and referenceBlock
