The question asks how many numbers from the given set: \(2037, 13754, 109911, 5863, 85657, 567952\) are divisible by 11.

To solve this, we will apply the divisibility rule for 11:
- The rule states that a number is divisible by 11 if the difference between the sum of its digits in odd positions and the sum of its digits in even positions is divisible by 11 (or zero).

Let's check each number:

1. **2037**:
   - Odd positions: \(2 + 3 = 5\)
   - Even positions: \(0 + 7 = 7\)
   - Difference: \(5 - 7 = -2\), not divisible by 11.

2. **13754**:
   - Odd positions: \(1 + 7 + 4 = 12\)
   - Even positions: \(3 + 5 = 8\)
   - Difference: \(12 - 8 = 4\), not divisible by 11.

3. **109911**:
   - Odd positions: \(1 + 9 + 1 = 11\)
   - Even positions: \(0 + 9 + 1 = 10\)
   - Difference: \(11 - 10 = 1\), not divisible by 11.

4. **5863**:
   - Odd positions: \(5 + 6 = 11\)
   - Even positions: \(8 + 3 = 11\)
   - Difference: \(11 - 11 = 0\), divisible by 11.

5. **85657**:
   - Odd positions: \(8 + 6 + 7 = 21\)
   - Even positions: \(5 + 5 = 10\)
   - Difference: \(21 - 10 = 11\), divisible by 11.

6. **567952**:
   - Odd positions: \(5 + 7 + 5 = 17\)
   - Even positions: \(6 + 9 + 2 = 17\)
   - Difference: \(17 - 17 = 0\), divisible by 11.

So, the numbers divisible by 11 are **5863, 85657, 567952**. Thus, the correct answer is **3 numbers**.

Answer: **B. 3**
