3. 25

4. 300

The correct answer is: 25

In Salesforce, the maximum number of lookup relationships that an object can have is 25. Lookup relationships are a type of relationship that link two objects together, allowing for a simple relationship where one object can reference another. This is beneficial for creating more complex data structures and enhancing data access within the Salesforce platform. Having 25 lookup relationships gives developers significant flexibility in designing their data models, enabling them to accurately represent real-world business processes and associations. It's essential for administrators and developers to understand this limit when designing their schema to ensure that they can implement all necessary relationships without surpassing this threshold. Though there are other types of relationships such as master-detail relationships and many-to-many relationships using junction objects, the numerical limit specifically for lookup relationships stands at 25. This means that for any single object, up to 25 distinct lookup relationships can be configured, enabling extensive data interconnectivity.
