Question
For the logic diagram provided, determine the logic expression for the output F.

### Logic Diagram
The diagram consists of three logic gates:
1. **AND Gate** (top left):
   - Inputs: A, B, C
   - Delay: 35 ns

2. **NOT Gate**:
   - Input: B
   - Output goes into the OR gate and another AND gate
   - Delay: 5 ns

3. **AND Gate** (bottom):
   - Inputs: B' (output from NOT gate), C
   - Delay: 25 ns

4. **OR Gate** (center):
   - Inputs: Outputs from the two AND gates
   - Delay: 25 ns
   - Output: F

### Logic Expression Options
- \( F = (A \cdot B \cdot C') \cdot (B \cdot C)' \)
- \( F = (A' \cdot B' \cdot C' + B' \cdot C)' \)
- \( F = (A \cdot B \cdot C \cdot B' \cdot C')' \)
- \( F = (A \cdot B \cdot C') + (B \cdot C')' \)

### Explanation 
Select the correct logic expression based on the diagram and the listed options. The total delay is measured from the path with the greatest cumulative gate delay, which affects the timing performance of the circuit.
