The prefix Lact- refers to which substance?

Explanation:
Lact- points to milk. It comes from the Latin lac, lactis, and shows up in terms like lactose (milk sugar), lactation (the production and secretion of milk), lactiferous (bearing or producing milk), and lacteal (a milky-looking lymphatic vessel). So the substance associated with this prefix is milk. Fat uses lip- or lipo-, bone uses oste- or osse-, and blood uses hem- or hemat-; none of those match the lact- meaning.
