(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 joined by hydrogen bonds. These are intermolecular hydrogen bonds,but the statement is often considered incorrect in specific contexts because it forms a layered structure where the sheets are held together by hydrogen bonds,and the internal structure is often described as having a specific network. However,the most technically incorrect statement is that it contains 'intermolecular' $H$-bonds in the context of its solid state structure,which is a layered network held by hydrogen bonding between layers.
