You want to improve the Trust Score™ of your dataset as a dataset owner.

Comprehensive and Detailed Explanation:

To enhance the Trust Score™ of a dataset:

Improve the quality of the dataset using Pipeline Designer (Option A):

Utilizing Talend's Pipeline Designer allows you to cleanse, transform, and enrich your data, thereby improving its quality and, consequently, its Trust Score™.​

Add ratings to the dataset (Option D):

Encouraging users to rate the dataset increases its popularity metric, positively impacting the overall Trust Score™.​

Why not other options?

Option B: The Trust Score™ is automatically calculated based on specific metrics; it cannot be manually altered.​

Option C: While using the dataset in ETL jobs indicates its utility, it does not directly influence the Trust Score™ unless it affects metrics like usage or popularity.​
