This is a prospective study because the researcher is following a group of pregnant women over time and collecting data on their use of fish oil supplements during pregnancy and the outcomes of their children's intelligence at 5 years of age. A case-control study compares individuals with a specific outcome to those without the outcome, but in this case, the researcher is comparing two different groups (women who took fish oil supplements during pregnancy and those who did not). In vivo refers to studies conducted within living organisms, which is not relevant to this study. Double-blind studies involve random assignment to an intervention or control group and blinding both the participants and researchers to which group they are in, which is also not relevant to this study.
