The instance type you are trying to launch may not be available in "ap-south-1-ccu-1a".  
You can search by way of the following documents.  
https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/instance-discovery.html  
https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/troubleshooting-launch.html#troubleshooting-instance-configuration

Since the location you are trying to activate seems to be in the local zone, it would be a good idea to check the following documentation.  
https://aws.amazon.com/about-aws/global-infrastructure/localzones/features/?nc1=h_ls
