Who are "we" in the pre-mortal life according to the LDS? From this link

In our premortal life, we were taught lessons that prepared us to
assist Heavenly Father in bringing about the salvation of His children
(see D&amp;C 138:56).

For a non Christian like me, especially English is not my mother language, it's difficult to understand a sentence which came from a Christian world.
That's why to me the word &quot;we&quot; in the quote is ambiguous since it can be:
A. We = the elects
B. We = all humankind
Hence the question.
B) all humankind
The next paragraph in the article states

The Prophet Joseph Smith explained that while in our premortal state, we were all present when God the Father explained His plan for the salvation of His children.
