Correct answer

d
all boom movements

wszystkie ruchy wysięgnika

Why?

E and C indicate lowering the boom sections (wysięgnik), while B indicates extending the telescope. In the configuration shown, these increase the working radius (wysięg) and load moment, so the load limiter (ogranicznik obciążenia) blocks them. It does not block every movement: retracting the telescope in direction A helps reduce the overload.
