Boron exhibits anomalous behavior in that it forms covalent compounds with hydrogen instead of ionic compounds. B_{2}H_{6}, also known as diborane, is an example of such a compound. Hence option A  is the correct answer.

Option (B) is incorrect because Al_{2}O_{3} is an ionic compound. Hence option B is incorrect.

Option (C) is incorrect because BF_{3} is a covalent compound, but it is not an example of the anomalous behavior of boron. Hence option C  is incorrect.

Option (D) is incorrect because GaAs s is an ionic compound. Hence option D is incorrect.
