Given below are two statements: one is labelled as Assertion \((A)\) and the other is labelled as Reason \((R)\) Assertion \((A)\) : Boron is unable to form \(BF _{6}^{3-}\) Reason \((R)\) : Size of \(B\) is very small. In the light of the above statements, choose the correct answer from the options given below.
- A Both \((A)\) and \((R)\) are true and \((R)\) is the correct explanation of \((A)\)
- B Both \((A)\) and \((R)\) are true but \((R)\) is not the correct explanation of \((A)\)
- C \((A)\) is true but \((R)\) is false
- D \((A)\) is false but \((R)\) is true
