Name the stage of the embryo in which all the body parts can be identified

Options

A. Zygote
B. Viviparous
C. Oviparous
D. Foetus

Explanation

**Step-by-Step Solution:**

1. **Understand the Embryonic Development Stages**: The development of an embryo occurs in several stages, starting from the zygote, which is formed after the fusion of male and female gametes.

2. **Identify the Early Stages**: Initially, the zygote undergoes cell division and forms a blastocyst. At this stage, the embryo is not yet recognizable as a developing organism.

3. **Recognize the Embryonic Stage**: As development continues, the embryo undergoes differentiation where various tissues and organs begin to form. This stage is known as the embryonic stage.

4. **Determine the Fetal Stage**: After several weeks of development, typically around the end of the first trimester (about 9 weeks), the embryo is referred to as a fetus. At this stage, all major body parts and organs can be identified, including limbs, head, and internal organs.

5. **Conclude with the Correct Answer**: Therefore, the stage of the embryo in which all the body parts can be identified is called the **fetal stage**.

**Final Answer**: The stage of the embryo in which all the body parts can be identified is the **fetal stage**.
