Answer 1

The correct option is B $\left(A\right)\to \left(ii\right),\left(B\right)\to \left(i\right),\left(C\right)\to \left(iv\right),\left(D\right)\to \left(iii\right)$

(A) Boron fibers $\to$ Boron carbide fibers and fiber composites may be used in the manufacture of ballistic materials for protective, durable and lightweight body armor. $\to$ (ii) Bulletproof vest

(B) Borax $\to$ used to produce various types of high strength and heat-resistant ceramic products. $\to$ (i) Heat-resistant glasses

(C) Aluminium $\to$ More than a quarter of all aluminium is used in the transport sector. $\to$ (iv) Transport industry

(D) Carbon black $\to$ Carbon black is mainly used as a reinforcing filler in tires and other rubber products. $\to$ (iii) Filler in automobile tyre
