Answer:
a. low birthweight
Explanation:
Normal gestation period is around 40 weeks before babies are being born with fully developed system and are capable of leading a normal life without intensive care. Preterm or premature birth are births that occur before the 37th week of pregnancy.
Average weight of full-term babies (babies born between 37–40 weeks) is around 7 pounds (3.17 kg) at birth, with a normal weight ranging from 5 lb 8 oz to 8 lb 13 oz.
