Question:medium

Given below are two statements: one is labelled as Assertion $A$ and the other is 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.
In the light of above statements, choose the most appropriate answer from the options given below:

Updated On: Mar 31, 2026
  • Both A and R are correct but R is NOT the correct explanation of A
  • Both A and R are correct and R is the correct explanation of A
  • A is incorrect and R is correct
  • A is correct but R is incorrect
Show Solution

The Correct Option is B

Solution and Explanation

To solve this problem, we need to analyze both the assertion and the reason and verify their correctness as well as the linkage between them.

  1.  Assertion A: "Steel is used in the construction of buildings and bridges."
    • This statement is correct. Steel is a fundamental material used in the construction industry due to its strength, durability, and ability to bear loads. It is commonly used in the construction of buildings and bridges, among other structures.
  2. Reason R: "Steel is more elastic and its elastic limit is high."
    • This statement is also correct. Elasticity refers to the ability of a material to return to its original shape after deformation. Steel exhibits high elasticity and has a high elastic limit, meaning it can withstand significant stress before permanently deforming, which is crucial in construction for handling loads and stresses.
  3. Link Between Assertion and Reason:
    • The reason explains why steel is widely used in construction. Its high elasticity and elastic limit make it suitable for withstanding stresses typical in buildings and bridges, ensuring safety and longevity.

The correct option is: "Both A and R are correct and R is the correct explanation of A."
