B. implantation of embryo at site other than uterus
C. implantation of defective embryo in the uterus
D. pregnancies terminated due to the hormonal imbalance

Explanation

### Step-by-Step Solution:

1. **Understanding Ectopic Pregnancy**:
- Ectopic pregnancy occurs when an embryo implants outside the uterus, which is different from a normal pregnancy where the embryo implants inside the uterus.

2. **Identifying the Site of Implantation**:
- The most common site for ectopic pregnancies is the fallopian tubes, but it can also occur in other areas such as the ovaries, abdominal cavity, or cervix.

3. **Terminology**:
- The term "Ectopic" refers to the abnormal location of the embryo. The specific term for an ectopic pregnancy in the fallopian tube is "Tubal Pregnancy" or "Echisis".

4. **Consequences of Ectopic Pregnancy**:
- Ectopic pregnancies cannot result in a viable pregnancy and often lead to complications, including the risk of rupture and internal bleeding, which can be life-threatening.

5. **Analyzing the Options**:
- Option 1: Pregnancy with genetic abnormality - Incorrect.
- Option 2: Implantation of embryo at a site other than the uterus - Correct.
- Option 3: Implantation of a defective embryo in the uterus - Incorrect.
- Option 4: Pregnancy is terminated due to hormonal imbalance - Incorrect.

6. **Conclusion**:
- The correct answer is that ectopic pregnancies are referred to as "Implantation of embryo at a site other than the uterus".
