The Southern colonies primarily farmed the following crops:
- Rice
- Tobacco
Grain was also grown in some areas, but it wasn't a primary crop of the Southern colonies compared to the aforementioned ones. Fish is not considered a crop, as it is a seafood product rather than an agricultural product.
So, the correct selections would be:
- Rice
- Tobacco
- Grain (to some extent)
If you need to choose only the main ones, then focus on rice and tobacco.
