Matching the site of injury with the potentially affected part:
\begin{itemize}
\item (A) Blow on lateral convexity of head: The middle meningeal artery runs beneath the temporal bone in the lateral aspect of the skull. A blow to this area is likely to damage the Middle meningeal artery (II), leading to an extradural hematoma.
\item (B) Blow over forehead: The anterior ethmoidal artery is located in the anterior cranial fossa, near the forehead. A fracture in this region can injure the Anterior ethmoidal artery (III).
\item (C) Blow over occiput: The transverse and sigmoid sinuses are located in the posterior cranial fossa, near the occiput. A blow to the occiput can potentially damage the Transverse sigmoid sinus (IV).
\item (D) Blow on vertex: The superior sagittal sinus runs along the midline at the vertex of the skull. A blow to the top of the head can injure the Sagittal sinus (I).
\end{itemize}
Therefore, the correct matching is (A)-(II), (B)-(III), (C)-(IV), (D)-(I).
