(D) $1$. Boron carbide $(B_4C)$ is extremely hard and is used as an abrasive.$2$. Boron is added to steel to increase its hardness and strength.$3$. Boron sesquioxide $(B_2O_3)$ is a key component in the production of borosilicate glass (e.g.,Pyrex).$4$. Orthoboric acid $(H_3BO_3)$ consists of layers of $BO_3^{3-}$ units held together by intermolecular hydrogen bonding,not intramolecular. Therefore,the statement claiming it has intramolecular $H$-bonding is incorrect.
