If A denotes `div` B, denotes `xx` C denotes +, D denotes- then which of the following statements is true ?

Options

A. 11 B 34 A 17 D 8 A3 `= (38)/(3)`
B. 6 B 18 D 26 A 13 C 7 ` = (173)/(13)`
C. 32 C 8 A 16 D 4 `= - (3)/(4)`
D. 9 C 9 A 9 d 9 B 9 = -71

Answer

To solve the problem, we need to decode the operations based on the given symbols:

- A denotes division (÷)
- B denotes multiplication (×)
- C denotes addition (+)
- D denotes subtraction (−)

Now, we will evaluate each option step by step to find out which statement is true.

### Step 1: Evaluate Option A
**Expression:** \( 34 \div 17 - 8 \div 3 \)

1. **Perform Division:**
- \( 34 \div 17 = 2 \)
- \( 8 \div 3 = \frac{8}{3} \)

2. **Substitute back into the expression:**
- \( 2 - \frac{8}{3} \)

3. **Convert to a common denominator:**
- \( 2 = \frac{6}{3} \)
- \( \frac{6}{3} - \frac{8}{3} = \frac{6 - 8}{3} = \frac{-2}{3} \)

**Result for Option A:** \( \frac{-2}{3} \)

### Step 2: Evaluate Option B
**Expression:** \( 6 \times 18 - 26 \div 13 \)

1. **Perform Division:**
- \( 26 \div 13 = 2 \)

2. **Substitute back into the expression:**
- \( 6 \times 18 - 2 \)

3. **Perform Multiplication:**
- \( 6 \times 18 = 108 \)

4. **Final Calculation:**
- \( 108 - 2 = 106 \)

**Result for Option B:** \( 106 \)

### Step 3: Evaluate Option C
**Expression:** \( 32 + 8 \div 16 - 4 \)

1. **Perform Division:**
- \( 8 \div 16 = 0.5 \)

2. **Substitute back into the expression:**
- \( 32 + 0.5 - 4 \)

3. **Perform Addition and Subtraction:**
- \( 32 + 0.5 = 32.5 \)
- \( 32.5 - 4 = 28.5 \)

**Result for Option C:** \( 28.5 \)

### Step 4: Evaluate Option D
**Expression:** \( 9 + 9 \div 9 - 9 \times 9 \)

1. **Perform Division:**
- \( 9 \div 9 = 1 \)

2. **Substitute back into the expression:**
- \( 9 + 1 - 9 \times 9 \)

3. **Perform Multiplication:**
- \( 9 \times 9 = 81 \)

4. **Final Calculation:**
- \( 9 + 1 - 81 = 10 - 81 = -71 \)

**Result for Option D:** \( -71 \)

### Conclusion
After evaluating all options, we find that:

- Option A: \( \frac{-2}{3} \)
- Option B: \( 106 \)
- Option C: \( 28.5 \)
- Option D: \( -71 \)

Since we need to determine which statement is true, we conclude that the correct option is **Option D**.
