The answer to this question would depend on the specific research data available. However, generally speaking:

1. Children are exposed to brands of fast food much more through television than product placements: This statement could be true. Television commercials for fast food brands are quite common and have a wide reach. However, product placements in movies, shows, and online content are also a significant source of exposure.

2. Children are exposed to brands of fast food much more in online environments than on TV: This statement could also be true, especially in recent years. With the rise of digital media, children are spending more time online where they encounter various forms of advertising, including for fast food brands.

3. Children are exposed to brands of fast food much more through advertising in store than online: This statement is likely less true. While in-store advertising can be impactful, it requires the child to be physically present in the store. Online advertising, on the other hand, can reach children wherever they are.

In conclusion, all three statements could be true to some extent, but the exact truth would depend on specific data and research.
