- ENone of the above/More than one of the above
Show answer and explanation
Correct answers: (a) Vitamin B1 - Oranges or (e) None of the above/More than one of the above
Explanation
The pairs (b), (c) and (d) are clearly correct: cod-liver oil is rich in vitamin D, wheat-germ oil in vitamin E, and alfalfa in vitamin K.
Oranges are known for vitamin C, but they also contain a small amount of vitamin B1. The book counts pair (a) as correct too and gives (e); many keys mark (a) as the pair that does not match.
The book gives (e), since oranges also contain a little vitamin B1; many keys give (a). Both are accepted here.
