To estimate the number of seeds in each flower pot, we can divide the total number of seeds by the number of flower pots:
\[ \frac{194 \text{ seeds}}{11 \text{ pots}} \approx 17.64 \]
Since we need to find the best estimate, we can round this to a nearby whole number. The closest options given are 10, 20, 30, and 40.
Among these, the best estimate is 20.
