            Which of the following network models are suitable for representing the topology of metabolic pathways in biological systems?
            1. **Small-world network** because it ensures high clustering, which represents functional metabolic clusters and pathways, while also having short path lengths for efficient chemical signaling.
            2. **Random network** because it randomly connects metabolites and enzymes, ensuring diverse and unpredictable interactions in the network.
            3. **Power-law network** because it produces a few highly connected nodes (hub enzymes) that play crucial roles in regulating key metabolic pathways.
            4. **Random network** because it results in efficient information transfer through a uniform distribution of connections between metabolites and enzymes.
