Respuesta :
The last sentence “I was not conscious after my head hit the ground.” Is the correct answer. The person was “not aware” or knocked out after hitting their head.
The correct answer is D.
Following the definitions, the last sentence is the only one who uses the word "conscious" with its correct meaning.
By saying that the person was "not conscious" after his head hit the ground, it is refering to a loss of consciousness, to a lack of awareness of surrondings, since the person has passed out because of the head injury.
