The following ChatGPT response—with numbered lines—answers the question: "What controls the elastic modulus of elastomers?" One of the lines contains an error in reasoning. Review the answer below and select the line with the incorrect reasoning.ChatGPT Response:1. The elastic modulus of elastomers is not primarily determined by atomic bonding forces.2. Instead, it arises from entropy-related effects due to the configurational freedom of long polymer chains.3. When stretched, the chains become more disordered, which increases entropy and resists deformation.4. This entropic resistance is why elastomers exhibit low but nonzero stiffness.5. Temperature also influences the modulus, since thermal energy affects chain mobility and entropy.Which line in the above response contains the incorrect reasoning?
