Correct Answer:
A. Full coverage leaf
Explanation:
The correct answer is Full cloverleaf.
A full cloverleaf interchange is a grade-separated intersection that allows traffic to move between two crossing highways without stopping. It features four circular loop ramps that handle right-turning traffic (in left-hand drive systems) or left-turning traffic (in right-hand drive systems), creating a shape resembling a four-leaf clover when viewed from above. This design eliminates the need for traffic signals or hazardous cross-traffic turns, ensuring a continuous flow of vehicles. While highly efficient for high-volume traffic, it requires a significant amount of land and can sometimes lead to weaving issues where vehicles entering and exiting the highway must cross paths in a short distance.
