The Assertion is true because boron does not form a stable compound with oxygen due to its small size and high electronegativity, which makes it difficult for boron to attract electrons from oxygen to form a stable compound. The Reasoning is also true because boron has a smaller size and higher electronegativity than oxygen, which makes it difficult for them to form stable compounds.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.
