Let's analyze each row of isotopes to identify which are isotopes of the same element.
### 1. (_10^23)W, (_9^25)X, (_10^25)Y, (_8^25)Z
- **Isotopes**: (_10^23)W and (_10^25)Y
**Explanation**: Isotopes of an element have the same atomic number (number of protons) but different mass numbers. In this case, (_10^23)W and (_10^25)Y both have an atomic number of 10 (indicating they are isotopes of the same element), while (_9^25)X has an atomic number of 9 and (_8^25)Z has an atomic number of 8, indicating they are different elements.

### 2. (_6^14)A, (_7^14)B, (_8^15)C, (_7^15)D
- **Isotopes**: (_6^14)A
**Explanation**: The isotopes of an element must have the same atomic number. In this case, (_6^14)A has an atomic number of 6, indicating it is carbon. On the other hand, (_7^14)B and (_7^15)D both have the atomic number of 7, indicating they are isotopes of nitrogen. (_8^15)C, having an atomic number of 8, is oxygen and not an isotope of carbon, nitrogen, or any of the other elements listed.

### 3. (_17^33)L, (_16^34)M, (_17^34)N, (_17^35)O
- **Isotopes**: (_17^33)L, (_17^34)N, (_17^35)O
**Explanation**: Isotopes of the same element have the same atomic number. Here, (_17^33)L, (_17^34)N, and (_17^35)O have the same atomic number of 17 (indicating they are isotopes of chlorine), while (_16^34)M has an atomic number of 16, indicating it is sulfur and not an isotope of chlorine.
---
In summary, the isotopes were identified based on their atomic numbers, where isotopes must share the same atomic number but vary in mass number.
### 1. (_10^23)W, (_9^25)X, (_10^25)Y, (_8^25)Z
- **Isotopes**: (_10^23)W and (_10^25)Y

In this case, (_10^23)W and (_10^25)Y both have an atomic number of 10 (indicating they are isotopes of the same element), while (_9^25)X has an atomic number of 9 and (_8^25)Z has an atomic number of 8, indicating they are different elements.

On the other hand, (_7^14)B and (_7^15)D both have the atomic number of 7, indicating they are isotopes of nitrogen. (_8^15)C, having an atomic number of 8, is oxygen and not an isotope of carbon, nitrogen, or any of the other elements listed.
