A. Option A
B. Option D
C. Option B

Answer: C

Explanation:
When you want a Lightning web component to only render for a specific form factor, you can use the <targets> tag within the component's .xml configuration file. To specify that the component should only appear on a desktop, you use the <targetConfig> tag with the targets="lightning__RecordPage" attribute and nest a <supportedFormFactors> tag inside it. Within this tag, you include a <supportedFormFactor> tag with the attribute type="Large".
Option B is the correct markup to ensure that the component only appears for the desktop form factor on a record page.
