Correct answer & explanation

Ensuring representative data and anonymizing PII are critical for model fairness and privacy. Removing all records with missing values can discard useful information; using only recent data may introduce bias; single-annotator labeling can cause subjective bias.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use only data from the last month.
Why it's wrong here
Using only recent data may miss long-term patterns and reduce sample size, harming model robustness.
- ✓
Ensure data is representative of all customer demographics.
Why this is correct
Representative data prevents model bias and improves generalization across customer segments.
- ✗
Remove all records with missing values.
Why it's wrong here
Removing all missing values may discard valuable data; imputation or handling missingness is preferred.
- ✗
Label data manually by a single annotator.
Why it's wrong here
Single-annotator labeling introduces individual bias; best practice is multiple annotators with consensus.
- ✓
Anonymize personally identifiable information (PII) before training.
Why this is correct
Anonymization protects customer privacy and complies with regulations like GDPR.
