Final answer:
Placental insufficiency, alcohol consumption, and undernutrition can lead to asymmetric growth restriction in a fetus.
Step-by-step explanation:
Asymmetric growth restriction in a fetus can be caused by various factors. One possible cause is placental insufficiency, which occurs when there is a problem with the placenta that prevents the transfer of oxygen and nutrients to the fetus. Another cause is alcohol consumption during pregnancy, which can lead to fetal alcohol spectrum disorder and result in cognitive deficits and developmental delays. Additionally, maternal undernutrition and intrauterine growth restriction can also contribute to asymmetric growth restriction in a fetus.
