Answer: D) "Cerebrospinal fluid oozing from the puncture wound."

Explanation:

The nail penetrates the skull about ½ inch that damages the dura, the outermost layer of the meninges and cause leaking of Cerebrospinal fluid.

A Cerebrospinal fluid (CSF) leak is caused due to the hole or tear in the meningeal layer. CSF leak can be furthur diagnosed with Computerized axial tomography (CT) and magnetic resonance imaging (MRI) is required to determine the location and severity of the leakage.

Hence, the correct option is D) "Cerebrospinal fluid oozing from the puncture wound."
