The word "Mathematics" is derived from the following Greek words: (a) Techne (b) Arsmathematica (c) Manthanein
(b) and (c)
Reference texts commonly trace the term to the Greek roots "Techne" (art or craft) and "Manthanein" (to learn), while "Ars Mathematica" is a later Latin phrase rather than a Greek word. This makes option (B), combining (c) and (a), the more defensible pick on etymological grounds, though the source booklet marks option (D). The discrepancy is flagged here for editorial review.
