Explanation
## Step 1The problem presents a statement about human development, specifically around week eight of gestation. The statement mentions the beginning function of several major organs such as kidneys, liver, brain, and lungs, and the formation of external genitalia. ## Step 2The statement is asking to fill in the blank with the appropriate term that describes this stage of human development. The options given are fetus, infant, neonate, and villus.## Step 3By analyzing the given information, we can determine that the description fits the definition of a fetus. A fetus is the term used to describe a developing human from the ninth week after conception until birth. This stage is characterized by the beginning function of major organs, the formation of fingers and toes, and the formation of external genitalia.## Step 4The term 'infant' refers to a child from birth to 1 year old, 'neonate' refers to a newborn baby, and 'villus' is a term used in the context of the small intestine, none of which fit the description given in the problem.## Step 5Therefore, based on the given information and the definitions of the terms, the correct answer is 'fetus'.
