In a creation code, 592 means ‘grapes are sweet’ 374 means ‘I like oranges’ and 267 means ‘oranges are sour’. Which digit represents sour? A. 9 B. 5 C. 6 D. Cannot be determined

'grapes are sweet' = 592 and 'oranges are sour' = 267 share only the word 'are', so are = 2. 'I like oranges' = 374 and 'oranges are sour' = 267 share only 'oranges', so oranges = 7. In 267, removing are (2) and oranges (7) leaves 6, so sour = 6.
