Answer :
C. within Stefano
Within literature, there are many times of conflict. Some of the types of conflict are Man vs. Man, Man vs. Nature, Man vs. Society, and Man vs. Himself. Man vs. Himself is a conflict that will happen inside the mind of a character and frequently manifests itself in indecision, uncertainty, or guilt. This is also known as internal conflict. As such, it is safe to say that internal conflict will take place “within” a character. Thus, the internal conflict in “The Colomber” occurs within Stefano.
