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

  • ABoth $A$ and $R$ are correct but $R$ is NOT the correct explanation of $A$
  • B$A$ is not correct but $R$ is correct
  • CBoth $A$ and $R$ are correct and $R$ is the correct explanation of $A$
  • D$A$ is correct but $R$ is not correct
