A, D

A, D

Correct answer

c
C, B

C, B

d
F, D

F, D

Why?

A means lowering the boom, and D means extending it. In the position shown, both increase outreach (wysięg) and load moment, so the load limiter (ogranicznik obciążenia) blocks them. B and C reduce outreach, allowing the overload condition to be relieved.
