You have just received a new dataset from a colleague.

Detailed Answer in Step-by-Step Solution:

Objective: Get summary info from an ADSDataset object.

Evaluate Options:

A: Correlation matrix—Specific, not full summary.

B: Converts to XGBoost—Not for summary.

C: Executes computation—Not summary-focused.

D: Displays summary (types, counts, dist)—correct.

Reasoning: show_in_notebook() provides a comprehensive overview.

Conclusion: D is correct.

OCI documentation states: “show_in_notebook() (D) from ADSDataset displays a summary of the dataset, including feature types, observation count, and distributions, in a notebook.” A is partial, B and C are unrelated—only D meets the need per ADS SDK.
