Which code corresponds to the description 'Reverse switch position route selection with northward initiation'?

Explanation:
Two-letter codes in these items compress both the action on the turnout and the direction of initiation. The description calls for reversing the switch position and selecting a route, with the initiation coming from the north. The code uses R to indicate reversing the turnout, and N to designate northward initiation. Put together, it precisely conveys “reverse the switch, northward initiation to set the route,” which is why this code fits the description best. The other codes would imply different actions or directions that don’t match the northward initiation requirement, so they don’t align with the given description.
