215 kg

c
115 kg

115 kg

Correct answer

d
80 kg

80 kg

Why?

The point at a height of 20 m and a horizontal outreach (wysięg) of 10 m is within the working envelope for a load (obciążenie) of 115 kg. A load of 215 kg is not permitted because its outreach limit is approximately 8.2 m. A load of 80 kg is also allowed, but the question asks for the maximum.
