Hello @sreenivasulu gundagula
Welcome to the Atlassian community.
Conditional display of fields based on other fields is not something that can be managed with Automation Rules.
For that you need a third party app. One app that might help you, depending on other factors of your scenario, is Behaviours for ScriptRunner.
