Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
By declaring the stylesheet in the component's js-meta.xml configuration file.
Why it's wrong here
Incorrect because metadata files do not declare local CSS bundles.
- ✗
By importing the CSS file explicitly at the top of the JavaScript file using an import statement.
Why it's wrong here
Incorrect because CSS is loaded automatically without explicit JS imports in standard LWC.
- ✓
Automatically by sharing the exact base file name in the same component bundle folder.
Why this is correct
Correct because LWC shadow DOM automatically bundles stylesheets sharing the component name.
- ✗
Using a <link rel="stylesheet"> tag inside the component HTML template.
Why it's wrong here
Incorrect because local stylesheets do not require link tags.
