The older men in the village commiserate with Okeke regarding Nnaemeka’s decision to disobey him.
We know that Nnaemeka has decided to disobey his father and the traditions because he decides to marry "a woman who spoke a different tongue". The correct answer to the question is that the older men in the village commiserate with Okeke. It says in the text, "This man had come with others to commiserate with Okeke when news went round about his son's behavior." Because of this evidence from the text the only answer can be that they commiserated with him.
