The data structure contains the haulmkilling **agents** and the **valid options** available in farmmaps.
**'inputCode'** needs to have a value that is gotten from the haulmkilling agent query.
**'agentName'** needs to have a value that is gotten from the haulmkilling agent query.
**'inputType'** needs to have a value that is gotten from the haulmkilling agent query.
**'selectedOption'** needs to have a value that is gotten from the haulmkilling agent query.
The given agent values(agentName, inputType and selectedOption) as specified above form a unique combination specifying correct agent data.
For example, the agent with **'agentName'** needs to have an entry of **'inputType'** with a constant object with the **"option"** key and value **'selectedOption'**.
