The scenario describes users seeing different picklist options based on the "kind of opportunity." This is the primary function of Record Types in Salesforce. Record Types allow administrators to offer different business processes, page layouts, and a subset of picklist values to users for different categories of records within a single object. To update the available options for a specific type of opportunity, the administrator must navigate to the settings for that Opportunity Record Type and edit the available values for the custom picklist field.

A. Fields and relationships: This section is used to define the master set of all possible values for a picklist field, not to control which values are available for different record types.

B. Related lookup filters: These are used to restrict records in lookup relationship fields, which is irrelevant for controlling values within a picklist field.

D. Picklist value sets: These allow a single master list of values to be shared across multiple picklist fields, but the control over which of those values are available is still managed at the Record Type level.

1. Salesforce Help Documentation

"Create Record Types": "Record types let you offer different business processes

picklist values

and page layouts to different users... For example

you can create a record type for sales deals and another for consulting engagements

with different picklist values for the Stage field for each." This directly aligns with the scenario of different options for different kinds of opportunities.

2. Salesforce Help Documentation

"Edit Picklists for Record Types and Business Processes": This guide provides the specific steps for the task described in the question. It states

"From the management settings for the object you want to edit

go to Record Types... For the record type you want to edit

click Edit next to the picklist field's name. From this page

you can change which values are included in the picklist."

3. Trailhead

"Administrator Certification Prep: UI and Layout" module

"Customize Record Details with Page Layouts and Record Types" unit: "With record types

you can associate different business processes and a subset of picklist values to different users based on their user profiles." This confirms that controlling subsets of picklist values is a core feature of Record Types.
