Answer:
A.
Step-by-step explanation:
"The Red Badge of Courage" is a book written by Stephen Crane. The novel is about a teenage boy, Henry Fleming, who enrolls himself in the military with the hope to earn glorification.
But once he enters into the military and battleground, his fear comes upon him and he begins to retreat from the war.
In Chapter 4, the incident when Henry is running towards the fighting is ironic because he just fled the battle. When Henry hears of the renewed battle, he wants to run toward the battle, from where he just fled.
Therefore, option A is correct.
