I believe that the word "glands" is incorrectly added to the group. My reasoning for this stems from the fact that the rest seem to show the process of reacting to an external stimuli. When reacting to an external stimuli in a quick manner, your body will use the neuron pathways it has created throughout itself. As the sensory neuron senses the stimuli, it sends the message up the neuron to the brain, where it makes the decision to react, sends it down the motor neuron and created movement. This all happens in a very quick manner, while glands secrete hormones much more slowly.
The correct answer would be option A: "The beauty of nature amid war". In the excerpt, the author mentions several traits of nature, emphasizing the beauty of the larks singing and then mentions "amid the guns below" so one could infer that there is a war going on.
Option B is incorrect because the author does not mention anything that could point to the scene being a graveyard. Option C is incorrect because the larks (on their own) are not the theme, they are merely a topic and option D is incorrect because the author does not mention anything about the war, except for the use of guns (resolving differences or not).
Oh! I know the answer to this riddle!
Is it TIME? Time flies without wings - Surely everyone's heard of time flying when you're having fun
Time stands if you're bored - It feels like forever before it runs out,
And time destroys everything even given enough of it :D
