JEE MAIN 2021

• A. (a)-(v), (b)-(ii), (c)-(iv), (d)-(i)
• B. (a)-(v), (b)-(iii), (c)-(ii), (d)-(i)
• C. (a)-(iv), (b)-(iii), (c)-(i), (d)-(ii)
• D. (a)-(v), (b)-(i), (c)-(ii), (d)-(iv)

Answer 1

The correct option is B (a)-(v), (b)-(iii), (c)-(ii), (d)-(i)

$Li$ - bearing for motor engines; (a)-(v)
$Na$ - coolant in fast breeder reactor; (b)-(iii)
$K$ - absorbent of $C{O}_2$; (a)-(ii)
$Cs$ - Photoelectric cell; (d)-(i)
