Detailed Explanation:
Rationale for Correct Answer:In Terraform, a data source reference follows the format:
data. < DATA_SOURCE_TYPE > . < NAME > . < ATTRIBUTE >
Here:
Data source type = vsphere_datacenter
Name = dc
Attribute = id
Therefore, the correct reference is:
data.vsphere_datacenter.dc.id
This correctly retrieves the id attribute from the declared data source and passes it to the resource argument.
Analysis of Incorrect Options (Distractors):
B. data.vsphere_datacenter.dc — Incorrect because it references the entire data object, not a specific attribute like id.
C. data.dc.id — Incorrect because it omits the data source type (vsphere_datacenter), making the reference invalid.
D. vsphere_datacenter.dc.id — Incorrect because it is missing the data. prefix required for data sources.
Key Concept:Proper data source referencing syntax: data. < type > . < name > . < attribute > .
