Steel is said to be more elastic than rubber because
Answer: (B) steel needs a much larger stress for the same strain
Concept. In physics, "more elastic" means a larger modulus of elasticity: more stress is needed for the same strain.
Step 1. Compare. Steel's Young's modulus ($\sim 2 \times 10^{11}$ Pa) is far larger than rubber's ($\sim 10^6$ Pa), so steel needs a much larger stress for the same strain.
Answer. Steel needs a much larger stress for the same strain (Option B).
