Which of the following statements about mannose-6-phosphate
receptors that bind and take up lysosomal hydrolases into lysosomal
transport vesicles is true?

A) They are transported to lysosomes, where they are
degraded.

B) They are degraded in late endosomes, allowing the release of
the lysosomal hydrolases.

C) They release the lysosomal hydrolases in the late endosomes
and are recycled in vesicles back to the Golgi.

D) They are transported to lysosomes, where they hold the
lysosomal hydrolases.
