c

70%
Correct answer
d
10%
10%
Why?
With the legs of the two-leg sling (zawiesie dwucięgnowe) at 45° from vertical, A is 70% of the capacity of the vertical-leg arrangement marked 100%. This follows from cos 45° ≈ 0.707, rounded to 70% in the diagram. The 90% value belongs to the adjacent 30° arrangement, not the 45° arrangement.
