input

"Here comes a perfectly valid argument: To start with, Agnes is a close friend of Matilde or a granddaughter of Ida. Now, not being a close friend of Geraldine is sufficient for being a close friend of Matilde and a granddaughter of Ida. It follows that it is not the case that Agnes is a close friend of Geraldine."
Is the argument, given the explicitly stated premises, deductively valid or invalid?
Options:
- valid 
- invalid
