Answer: C

Explanation:

lookup retrieves the value of a single element from a map, given its key. If the given key does not exist, the given default value is returned instead. In this case, the function call is searching for the key "c". But since there is no key "c", the default vault "what?" is returned. https://www.terraform.io/docs/configuration/functions/lookup.html
