In service console when we send a survey to student or someone we have to select a mail right there i am not getting any option can anyone sort it out

Hello @Prasanth Sanapala

Make sure you have a Global Action that has its default name: SendEmail. 

There are three more things to keep in mind for this to work: 

1. Ensure Setup > Deliverability > Access to Send Email org wide pref is set to "All Emails" (this is OFF by default in Sandbox orgs, and also on trial orgs which haven't verified the user email address) 

2. Ensure the user has the Send Email user perm (which also adds the Edit Tasks user perm) 

3. Ensure that the Send Email Action is added to Lightning Actions in the Page Layout. 

Please note these three are requirements of the feature, not part of the Bug.
