Question

Given below are two statements, one is labelled as Assertion(A) and other one labelled as Reason(R).
Assertion (A): Steel is used in the construction of buildings and bridges.
Reason (R): Steel is more elastic and its elastic limit is high.

• A. Both (A) and (R) are correct and (R) is the correct explanation of (A).
• B. Both (A) and (R) are correct but (R) is NOT the correct explanation of (A).
• C. (A) is correct but (R) is incorrect.
• D. (A) is incorrect but (R) is correct.
• E. Both A and R are not correct

Hint:

In Physics, remember: Elasticity $\neq$ Stretchiness. A material is "more elastic" if it offers more resistance to being deformed and returns to its shape more effectively. This is why steel is technically more elastic than rubber! For Assertion-Reason questions, check both statements individually first, then examine if the reason logically explains the assertion.

Answer 1

The Correct Option is A
