D. 32cm,650gm.

Answer

To determine the height and weight of a twelve-week-old human embryo, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Gestation Period**:
- The human gestation period is approximately 9 months, which is about 40 weeks. During this time, the embryo and later the fetus undergo significant growth and development.

**Hint**: Remember that the gestation period is crucial for understanding fetal development stages.

2. **Identify the Developmental Stage**:
- At 12 weeks, the embryo is transitioning into the fetal stage. This is an important milestone in human development.

**Hint**: Know the difference between embryo and fetus stages; the 12-week mark is significant for fetal development.

3. **Research Average Measurements**:
- At 12 weeks, the average height of a human embryo is approximately 6 cm. This measurement reflects the overall length from the crown to the rump.

**Hint**: Look for standard growth charts or medical references for fetal measurements at various weeks.

4. **Determine Average Weight**:
- The average weight of a 12-week-old human embryo is about 14 grams. This weight can vary slightly from one embryo to another but serves as a general guideline.

**Hint**: Remember that weight can vary based on multiple factors, including genetics and maternal health.

5. **Summarize the Findings**:
- Therefore, the height of a twelve-week-old human embryo is approximately 6 cm, and its weight is about 14 grams.

**Hint**: When summarizing, always include both height and weight for clarity.

### Final Answer:
- The height of a twelve-week-old human embryo is approximately **6 cm**, and the weight is about **14 grams**.
