Introduction:
The story mentions that a story was spread throughout the whole village. The question asks who spread the story, and the correct answer is option 'A', a lady.

Explanation:
The story does not explicitly mention the name of the lady who spread the story, but it can be inferred from the context of the story. Let's analyze the details provided in the story to understand why the correct answer is option 'A'.

Taro's Father:
Taro's father is mentioned in the story, but there is no indication that he spread the story. The story states that Taro's father went to the city to sell vegetables, and when he returned, Taro shared the story with him. However, there is no mention of Taro's father spreading the story throughout the village.

A Man:
A man is mentioned in the story, but he is described as being the one who spread the story about the big reward for the person who could catch the kappa. This man's action is different from spreading the story throughout the village. He only spread the information about the reward, not the story itself.

Taro:
Taro is the main character of the story, and he is the one who witnesses the kappa and eventually catches it. However, the story does not mention Taro spreading the story throughout the village. Taro's actions are focused on catching the kappa and receiving the reward.

A Lady:
Although the story does not provide specific details about the lady who spread the story, it can be inferred from the context. After Taro catches the kappa and brings it to the lord, the story states that "the news of Taro's adventure spread like wildfire throughout the village." This implies that someone spread the news, and since the correct answer is option 'A', it can be concluded that a lady spread the story throughout the whole village.

Therefore, based on the information provided in the story, it can be determined that a lady spread the story throughout the whole village.
