The following Screen
(https://drive.google.com/file/d/1gm2xpbBQmE-KTAHtCdj4wT0jNLnpDzZX/view?usp=sharing) has two
Dropdowns, one to select a Country and one to select a City. The GetCountries and GetCities Aggregates
provide the countries and the cities to be displayed in the respective dropdowns and are both set to be fetched
At Start. Which of the following options is not a valid step if we want to just fetch the cities for the country
selected in the respective dropdown?
