The correct answer is $19$. The minimum value of a data set is the least value in the data set. The frequency refers to the number of times a value occurs. The given table shows that for this data set, the value $19$ occurs $7$ times, the value $21$ occurs $1$ time, the value $23$ occurs $7$ times, and the value $25$ occurs $4$ times. Therefore, of the values $19$, $21$, $23$, and $25$ given in the data set, the minimum value of the data set is $19$.
