Multiple Choice
- First
- Second
- Third
Solution
The answer to the question is the First trimester.
Explanation:
The first trimester of pregnancy is especially critical because it is during this time that the foundational development of the fetus occurs. This period spans from conception to the end of week 12, during which essential systems and structures of the body begin to form. Poor nutrition or exposure to harmful substances, such as drugs, can interfere with these crucial developmental processes, leading to potential birth defects. The neural tube, which becomes the brain and spinal cord, develops within the first few weeks, making proper prenatal nutrition and the absence of harmful substances vital for the health of the developing fetus.
