Explanation

Let's solve the question step by step.

### Question:
State 'T' for true and 'F' for false and select the correct option.

1. Set-squares are useful to draw parallel lines.
2. \( 13.5 + \frac{4}{8} + \frac{9}{8} + 8 + \frac{6}{8} > 12.5 + \frac{5}{2} + 8 + 14.6 \)
3. Zero is less than every negative number.
4. 4 more than -7 is -3.

### Step-by-Step Solution:

**(i) Set-squares are useful to draw parallel lines.**

- **Analysis**: Set-squares are indeed tools used in geometry to help draw parallel lines.
- **Conclusion**: This statement is **True (T)**.

---

**(ii) Evaluate the expression: \( 13.5 + \frac{4}{8} + \frac{9}{8} + 8 + \frac{6}{8} > 12.5 + \frac{5}{2} + 8 + 14.6 \)**

1. **Calculate the Left-Hand Side (LHS)**:
- Convert mixed fractions to improper fractions:
- \( \frac{4}{8} = 0.5 \)
- \( \frac{9}{8} = 1.125 \)
- \( \frac{6}{8} = 0.75 \)
- Now, add the values:
- \( 13.5 + 0.5 + 1.125 + 8 + 0.75 \)
- \( = 13.5 + 0.5 = 14 \)
- \( 14 + 1.125 = 15.125 \)
- \( 15.125 + 8 = 23.125 \)
- \( 23.125 + 0.75 = 23.875 \)

2. **Calculate the Right-Hand Side (RHS)**:
- Convert mixed fractions:
- \( \frac{5}{2} = 2.5 \)
- Now, add the values:
- \( 12.5 + 2.5 + 8 + 14.6 \)
- \( = 12.5 + 2.5 = 15 \)
- \( 15 + 8 = 23 \)
- \( 23 + 14.6 = 37.6 \)

3. **Compare LHS and RHS**:
- \( 23.875 > 37.6 \) is **False**.

- **Conclusion**: This statement is **False (F)**.

---

**(iii) Zero is less than every negative number.**

- **Analysis**: On a number line, zero is at the center, and all negative numbers are to the left of zero. Therefore, zero is greater than all negative numbers.
- **Conclusion**: This statement is **False (F)**.

---

**(iv) 4 more than -7 is -3.**

1. **Calculate**:
- 4 more than -7 means \( -7 + 4 \).
- \( -7 + 4 = -3 \).

- **Conclusion**: This statement is **True (T)**.

---

### Final Answers:
- (i) T
- (ii) F
- (iii) F
- (iv) T

### Correct Option:
The correct option is the one that matches: T, F, F, T.
