Having trouble applying the rules for simplifying this block diagram. Please explain how to simplify. Thanks!

**Simplify the following block diagram:**

### Block Diagram Description:
The diagram consists of a series of blocks connected with lines that indicate the flow of signals. 

- **Input and Output:**  
  - Input: \( R(s) \)
  - Output: \( C(s) \)

- **Blocks:**  
  - There is a block with a transfer function of \( \frac{1}{s} \).
  - Another block has a transfer function of \( 2 \).
  - There is a block with a gain of 5.
  - Another block has a transfer function of \( 2s \).

- **Summing Junctions:**  
  - There is a summing junction with inputs \( R(s) - 5 \) and an output connected to the \( \frac{1}{s} \) block.
  - Another summing junction follows the \( \frac{1}{s} \) and 2 blocks, with their outputs added and then fed into the \( 2s \) block.
  - Negative feedback is provided from the output of the \( 2s \) block back to the summing junction just before it.

### Options for Simplification:

(a) \(\frac{C(s)}{R(s)} = \frac{2}{s^2 + 3s + 5}\)

(b) \(\frac{C(s)}{R(s)} = \frac{2s}{3s + 5}\)

(c) \(\frac{C(s)}{R(s)} = \frac{2s + 3}{s^2 + 3s + 5}\)

(d) \(\frac{C(s)}{R(s)} = \frac{2s^2 + 2}{3s + 5}\)

(e) None of the above

Choose the correct simplification from the given options for the block diagram.
