Answer
Correct Answer: C. Ratio of stress to strain is more
Detail about MCQs
Steel is more elastic than rubber because:
C. Ratio of stress to strain is more
Elasticity is characterized by the ratio of stress to strain, known as the Young’s modulus. Steel, being a material with a high Young’s modulus, has a higher ratio of stress to strain compared to rubber, which means it is more elastic. Rubber has a lower Young’s modulus and thus is less elastic.
