Glands Krause & Wolfring produce the watery layer of tear film in conjunction with the lacrimal gland.

Explanation:
Tear film has three layers: lipid, watery (aqueous), and mucin. The watery layer, which is the majority of tear volume, is produced by the lacrimal gland along with its accessory glands Krause and Wolfring. That’s why this option is the best fit—the watery/aqueous portion comes from these glands working with the lacrimal gland. The mucin layer comes from goblet cells and helps the tear film spread, while the lipid layer from the meibomian glands reduces evaporation.
