**Understanding Logic Gates: Identifying Faulty Gates**

In the given diagram, we have six logic gates labeled from (a) to (f). Each gate has a set of inputs and a corresponding output.

1. **Gate (a):**
   - Inputs: 1, 1
   - Output: 0
   - This is an AND gate. For an AND gate, the output should be 1 when both inputs are 1. This gate is faulty.

2. **Gate (b):**
   - Inputs: 0, 1
   - Output: 1
   - This is an OR gate. For an OR gate, the output is correct because one of the inputs is 1. This gate is not faulty.

3. **Gate (c):**
   - Inputs: 0, 0
   - Output: 0
   - This is an OR gate. The output is correct since both inputs are 0. This gate is not faulty.

4. **Gate (d):**
   - Inputs: 0, 1, 1
   - Output: 0
   - This is an AND gate. For an AND gate, the output should be 1 if all inputs are 1. This gate is faulty.

5. **Gate (e):**
   - Inputs: 1, 0
   - Output: 0
   - This is an AND gate. The output is correct because one of the inputs is 0. This gate is not faulty.

6. **Gate (f):**
   - Inputs: 1, 1
   - Output: 0
   - This is an AND gate. The output should be 1 when both inputs are 1. This gate is faulty.

Based on the analysis, the faulty gates are:

- Gate (a)
- Gate (d)
- Gate (f)

**Answer Options:**

- a, b, and c.
- b, c, and f.
- b, c, and e.
- None of the above.

The correct faulty gates are **a, d, and f**, which do not match any given answer choice. Therefore, the answer is **None of the above.**
