Show answer & explanation
Concept:
In an interleaved figure series, compare alternate positions as separate subsequences. Track each movable marker independently by its direction and its fixed angular step.
Application:
The missing panel belongs to the even-positioned subsequence, so follow that subsequence across its known members to its next member.
The arrow-ended arm turns 45 degrees clockwise: left, then up-left, then up.
The dot-ended arm turns 90 degrees counterclockwise: down-left, then down-right, then up-right.
Combining the two next positions gives an upward arrow and a dot-ended arm directed up-right from the joint.
Cross-check:
The change between the known members of the even-positioned subsequence uses exactly the same two angular steps. The figure with an upward arrow and an up-right dot-ended arm is the only offered figure that preserves both movements.
Result:
Therefore, the required figure has an upward arrow and a dot-ended arm pointing up-right.
