Final answer:
The example of a calque is (d) jardin d'enfants - Kindergarten. The other pairs are examples of borrowing (a), loanword (b), and idiomatic expression (c) respectively.
Step-by-step explanation:
The pair that contains an example of a calque is (d) jardin d'enfants (French "garden of children") - Kindergarten (German "children garden"). A calque, also known as a loan translation, is a word or phrase borrowed from another language by literal, word-for-word or root-for-root translation.
For the other pairs: (a) The term footobooru in Japanese is a borrowing from the English word football, where the original English term is adapted into the phonetic system of the borrowing language. (b) The Hungarian word tre\u00e9ning is a loanword from the English training, meaning it is taken directly from English without translation, but adjusted phonetically.
(c) The Spanish phrase luna de miel translates to "moon of honey" in English and is an example of an idiomatic expression that parallels the English honeymoon, but is not a direct calque.
