* Option A is correct because talking to users is one of the best ways to understand their needs, goals, and pain points. By spending more time with them, you can identify the impact they seek from your product and how your features align with that impact. This will help you validate your assumptions and learn from your customers12.
* Option B is incorrect because disabling features that have never been used is a risky and potentially harmful action. It may cause frustration and confusion for the users who rely on those features, or who may want to use them in the future. It may also damage your reputation and trust with your customers. Instead of disabling features, you should seek feedback from your users and understand why they are not using them34.
* Option C is correct because running experiments is a powerful way to increase your understanding of what customers find valuable. By testing different hypotheses and measuring the outcomes, you can learn from your data and evidence. You can also use experiments to validate your ideas and assumptions before investing in building features5 .
* Option D is correct because examining whether the rarely used features solve the intended problem is a crucial step to evaluate your product performance. You should review your product vision and goals, and assess how your features contribute to them. You should also analyze the feedback and data you have collected from your users and stakeholders, and identify any gaps or mismatches between your features and their needs .
