Final answer:
The capabilities of the Schema Builder include creating custom objects, lookup relationships, and master-detail relationships. It does not allow creating standard objects, nor exporting a schema to another org directly.
Step-by-step explanation:
The Schema Builder in Salesforce is a powerful tool that offers several capabilities to design and modify the data model within Salesforce. When answering the question about the capabilities of the Schema Builder, we should look at the options provided: Create custom objects: Schema Builder allows users to create custom objects which are new object types that can be tailored to specific business needs. Create lookup relationships: It also enables the creation of lookup relationships that link objects together so that users can specify how records in one object relate to records in another object.
Create master-detail relationships: Additionally, the Schema Builder can be used to create master-detail relationships, which is a type of linkage between objects that defines a tight relationship where the detail record inherits sharing, security, and other aspects from the master record. Regarding the other options: (a) Schema Builder does not allow users to create standard objects as they are predefined by Salesforce. (e) It does not have the functionality to export a schema to another org directly, this requires using tools like change sets or the Salesforce deployment API.
