- A. Select the Helm chart media type with operation: extract
- B. Select the Helm chart media type with operation: copy
- C. Leave layerSelector out, since charts are always copied
- D. Select the image config layer with operation: copy

**Answer:** Select the Helm chart media type with operation: copy

**Explanation:** layerSelector picks a layer by media type, here application/vnd.cncf.helm.chart.content.v1.tar+gzip. The default operation, extract, unpacks the layer; copy keeps the chart tarball unchanged, which is how the HelmRelease docs configure it. Without a layerSelector, the first layer is extracted.
