Introduction:
The king's decision to prohibit further discussion about the Hilsa fish is based on the fact that everyone has been talking about it for a long time. This answer option suggests that the king wants to divert the attention of the people from this topic and focus on something else.

Explanation:
1. Long-term discussions:
One possible reason behind the king's decision is that discussions about the Hilsa fish have been going on for a significant duration of time. This can create monotony and boredom among the people as they repeatedly hear about the same thing. The king might believe that it is important to introduce new and diverse topics of conversation to keep the people engaged and interested.

2. Variety of discussions:
By limiting the discussion about the Hilsa fish, the king encourages the people to explore other subjects. This not only brings freshness to the conversations but also broadens their knowledge and perspectives. It prevents the people from getting fixated on a single topic and allows them to explore a wide range of interests.

3. Avoiding repetition:
Constantly discussing the same topic can lead to redundancy and lack of productivity. The king's decision to discourage further talk about the Hilsa fish indicates his desire to avoid repetition and ensure that the people engage in meaningful and diverse conversations. This promotes intellectual growth and prevents the stagnation of ideas.

4. Addressing the king's preferences:
Although the answer option doesn't explicitly state it, the king's personal preferences may also play a role in his decision. The king might not have liked the Hilsa fish or found the discussions about it to be trivial and uninteresting. By putting an end to these discussions, the king can create an environment that aligns more with his own preferences and interests.

Conclusion:
The prohibition on further talk about the Hilsa fish is driven by a combination of factors. The long duration of discussions, the need for variety, the avoidance of repetition, and possibly the king's personal preferences all contribute to this decision. By redirecting the conversations towards different subjects, the king aims to keep the people engaged and interested in a wider range of topics.
