Some companies have a culture where everything is discussed in meetings, and if you aren’t in all the meetings none of the context is anywhere else to be found.
The best thing to do (if you want to catch up) is ask someone who seemed to know what was going on to get you up to speed after the meeting. Or, if you don’t, just try to get out of the meetings. Nobody realised you had no idea what was going on.. they probably won’t notice if you weren’t there at all.
I think none of those, one that is focused on teaching and explaining your reasoning would be better. You can always do it humbly because the author may have some info you don’t that they came across when implementing, which is why it is the way it is.
