A prospective study is one that follows a group of individuals over time to investigate the potential relationship between an exposure (in this case, taking fish oil supplements during pregnancy) and an outcome (higher intelligence scores in children at 5 years of age). This type of study would be appropriate for investigating this research question. In-vivo studies typically refer to experiments conducted in living organisms, double-blind studies refer to a study design where neither the researchers nor the participants know which group they belong to in terms of treatment or control, and case-control studies are a type of observational study that compares individuals with a particular outcome (cases) to those without the outcome (controls). These study designs would not be appropriate for investigating the research question posed in this scenario.
