Explanation

To solve the question regarding the effects of hypothyroidism during pregnancy on the developing baby, we will analyze each option provided in the question step by step.

### Step-by-Step Solution:

1. **Understanding Hypothyroidism**:
- Hypothyroidism is a condition where the thyroid gland does not produce enough thyroid hormones (like thyroxin). During pregnancy, this can lead to various developmental issues in the fetus.

2. **Analyzing the Options**:
- **Option A: Cretinism (stunted growth)**:
- Correct. Cretinism is a condition resulting from severe hypothyroidism during pregnancy, leading to stunted growth and developmental delays in the baby.

- **Option B: Dwarflism**:
- Incorrect. Dwarflism is generally associated with genetic factors and not specifically linked to hypothyroidism.

- **Option C: Mental retardation**:
- Correct. Hypothyroidism can lead to inadequate development of the central nervous system, resulting in mental retardation.

- **Option D: Low intelligence quotient**:
- Correct. Due to the effects of hypothyroidism on brain development, the child may have a low IQ.

- **Option E: Abnormal skin**:
- Correct. Thyroid hormones play a role in skin health, and hypothyroidism can lead to skin abnormalities.

- **Option F: Deaf-mutism**:
- Correct. Hypothyroidism can affect speech and hearing development, leading to conditions such as deaf-mutism.

3. **Conclusion**:
- The correct options that relate to the effects of hypothyroidism during pregnancy on the developing baby are A (Cretinism), C (Mental retardation), D (Low intelligence quotient), E (Abnormal skin), and F (Deaf-mutism).
- Therefore, the answer includes options A, C, D, E, and F.

### Final Answer:
The effects of hypothyroidism during pregnancy lead to:
- Cretinism (stunted growth)
- Mental retardation
- Low intelligence quotient
- Abnormal skin
- Deaf-mutism
