Construct an Unbinned Frequency Table for the Numbers of Persons

Construct an unbinned frequency table for the numbers of persons with various blood types. $\begin{array}{llllllllll}\mathrm{O} & \mathrm{A} & \mathrm{A} & \mathrm{O} & \mathrm{O} & \mathrm{AB} & \mathrm{O} & \mathrm{B} & \mathrm{A} & \mathrm{O} \\\mathrm{A} & \mathrm{O} & \mathrm{A} & \mathrm{B} & \mathrm{O} & \mathrm{O} & \mathrm{O} & \mathrm{AB} & \mathrm{A} & \mathrm{A}\\\mathrm{A} & \mathrm{B} & \mathrm{O} & \mathrm{A} & \mathrm{A} & \mathrm{O} & \mathrm{O} & \mathrm{B} & \mathrm{O} & \mathrm{O} \\\mathrm{O} & \mathrm{A} & \mathrm{O} & \mathrm{O} & \mathrm{A} & \mathrm{B} & \mathrm{O} & \mathrm{O} & \mathrm{A} & \mathrm{AB}\end{array}$
Create a frequency table for the data.

A)
$\begin{array}{l|c}\text { Blood type } & \text { Frequency } \\\hline \mathrm{O} & 20 \\\mathrm{~A} & 13 \\\mathrm{~B} & 4 \\\mathrm{AB} & 3\end{array}$

B)
$\begin{array}{l|c}\text { Blood type } & \text { Frequency } \\\hline \mathrm{O} & 19 \\\mathrm{~A} & 11 \\\mathrm{~B} & 5 \\\mathrm{AB} & 2\end{array}$

C)
$\begin{array}{l|c}\text { Blood type } & \text { Frequency } \\\hline \mathrm{O} & 19 \\\mathrm{~A} & 13 \\\mathrm{~B} & 5 \\\mathrm{AB} & 3\end{array}$

D)
$\begin{array}{l|c}\text { Blood type } & \text { Frequency } \\\hline \mathrm{O} & 18 \\\mathrm{~A} & 14 \\\mathrm{~B} & 5 \\\mathrm{AB} & 3\end{array}$
