Ответ:

"We've been here for four weeks." - Explanation c: A past action which has a result in the present. In this case, the action of being in a place (here) for four weeks has a result or consequence in the present - the speaker is still in that place.

"I've met lots of interesting people." - Explanation b: An action that happened at an unspecified moment in the past. The sentence talks about a past action (meeting people), but it doesn't specify when these meetings occurred.

"I've just realized something." - Explanation d: An action which finished very recently. The use of "just" indicates that the realization happened very recently, and it is still relevant in the present.

"I've made a timetable. It's on my wall." - Explanation a: An action which started in the past and continues in the present. The action of making a timetable started in the past and the result, the timetable being on the wall, continues to exist in the present.
