Answer:

Option B

Step-by-step explanation:

During the third trimester, the fetus continues to grow in weight and size however the body systems finish maturing. In fact, both mother’s body and the fetus continue to grow and change. Lungs, brain and kidneys keep maturing. Fetus position itself head-down and is 6 to 9 pounds in weight. Skull bones are soft but fetus become able to suck its thumb and cry. By 38 to 40 weeks, the lungs have matured fully . The end of third trimester marks the period when the fetus is ready for delivery. Hence option B is the correct answer
