The question asks what does the board mean.
I thought it meant that after 1500m, the speed limit on the right lane is then 70km/h and the speed limit in the middle and left lane is 90km/h?
The answer says something else.

The question is not about the middle or the left lane, only about the right lane.

The question is if the meaning of the traffic sign is:

A. that frome here until 1500 m ahead, the speed limit on the right lane is 70 km/h.

B. that [starting at] 1500 m ahead from here, the speed limit on the right lane is 70 km/h.
