An HR manager needs a cited comparison of how several organizations in her sector structure parental-leave policies, drawing on many public sources. Which approach is most appropriate?

Answer: C — Use Claude's research feature to synthesize many sources into a cited report, then check the key claims.

A multi-source comparison that needs citations fits research, which searches across sources and returns a cited report; the claims the decision rests on still need checking (c). Built-in knowledge alone (a) may be outdated and uncited. An internal document (b) gives Claude nothing about other organizations. Generated 'typical' examples (d) are invented, not researched.
