SOQL is primarily used for what type of relationships in Salesforce?

SOQL, or Salesforce Object Query Language, is designed to work effectively within the Salesforce data model, allowing users to query and retrieve specific data from Salesforce objects. The correct answer highlights that SOQL is particularly suited for both child-to-parent and parent-to-child relationships.

In child-to-parent relationships, SOQL enables you to query child records while retrieving related parent field values. For instance, if a query is made on a child object like Contacts, you can easily access and include relevant fields from the associated Account (the parent). This type of querying is essential for pulling related information efficiently without needing separate queries or manual lookups.

On the other hand, in parent-to-child relationships, SOQL allows you to query a parent record and include child records through subqueries. This capability is crucial in scenarios where you need to analyze or report data encompassing both sides of the relationship, effectively leveraging the hierarchical nature of related records.

While option one refers to a specific tier of relationships (parent-to-grandchild), it doesn't encompass the broader capabilities provided by SOQL. The option about one-to-many relationships and the many-to-many option do not capture the specific child-to-parent and parent-to-child querying functionalities that SOQL supports, which are essential in relational data handling within
