Answer: (A), (D)

The correct options are

A. Osteocytes are the cells that don't divide after birth and the number remains the same and may decrease with age as they can't replicate and some may die.

B. The muscle cells can replicate in the body like for example they increase in size as the age increases from child to adult which is possible due to the replication of the muscle cells.

C. The germ cells can replicate and convert to their particular cells like they are specific for RBC, nerves, etc.
