C	The embryo can see light.
D	The embryo has a heartbeat

Explanation:

Detailed explanation-1: -The heart of an embryo starts beating at about week 5 of pregnancy. It may be possible to detect the heartbeat at this point using vaginal ultrasound. Throughout the pregnancy and delivery, healthcare professionals monitor the heartbeat of the fetus.

Detailed explanation-2: -The average fetal heart rate is between 110 and 160 beats per minute. It can vary by 5 to 25 beats per minute. The fetal heart rate may change as your baby responds to conditions in your uterus. An abnormal fetal heart rate may mean that your baby is not getting enough oxygen or that there are other problems.
