You need to import a pre-built workflow into Fusion SOAR to automate a part of...

The best-supported answer is D. .YAML .

CrowdStrike’s recent Falcon Fusion SOAR technical content shows workflow structures represented in YAML . In particular, CrowdStrike’s workflow-based pagination example for Falcon Fusion SOAR says, “The following YAML shows the workflow structure,” and then provides the workflow definition in YAML form. That indicates YAML is the workflow definition format used in documented examples for reusable/pre-built workflow structures.

Why the other options are incorrect:

A (.CPP) and C (.PY) are programming language source files, not workflow import formats for Fusion SOAR. B (.JSON) is heavily used elsewhere in the platform for schemas, API payloads, and structured data, but the CrowdStrike materials I found that specifically show workflow structure present it in YAML , not JSON. Based on that documented workflow representation, .YAML is the correct answer here.
