Explanation:
In traffic signals, a sign with an arrowhead pointing left usually implies option A, which is 'Left turn only'. It communicates to drivers that they must turn left at that intersection. It's typically used in roads where there is a unique lane dedicated to left turns or to guide the traffic flow efficiently and prevent accidents or traffic jams.
The other options like 'No left turn allowed', 'Merge to the left', or 'One-way traffic to the left' have totally different signs. Understanding these signs and what their arrowheads represent is crucial to safe and effective driving.
