Final Answer : C, Explanation :  The formation of the arms and legs of an embryo occurs around the fifth week of pregnancy. During this time, the limb buds appear and over the course of a few weeks they develop into arms, legs, hands, and feet. It is during this stage that the basic pattern of the limbs is established. The second week of pregnancy is when implantation occurs, the twelfth week is when the fetus starts to look more human-like and the first week is when fertilization occurs.
