The Assertion is true because Boron and Silicon exhibit a diagonal relationship due to their similar properties, which arises due to the similarity in their atomic size and electronic configuration. The Reasoning is also true because both boron and silicon have similar atomic radii and valence electrons. Hence option A is the correct answer.

Option(2) Both assertion and reason are true and the reason explains assertion correctly. Hence option 2 is incorrect.

Option(3) Both assertion and reason are true. Hence option 3 is incorrect.

Option(4) Both assertion and reason are true. Hence option 4 is incorrect.
