C As sperm mature, they migrate from the seminiferous tubules into the lumen.

Explanation:

Answer C is false. Different types of germline cells migrate through the seminiferous tubes into the lumen, but not the sperm. Primary spermatocytes located near the basal lamina of the seminiferous tube generate secondary spermatocytes (through meiosis 1) that are located closer to the lumen in relation to the primary spermatocytes; in turn, secondary spermatocytes generate spermatides (through meiosis 2) that are even closer to the lumen. Finally, the spermatides are transformed into sperm through spermatogenesis. Sperms are located very close to the lumen to be released into the lumen through spermiogenesis.
