Choose the correct answer from the options given below:

$Y$ $\xleftarrow{\Delta ,\, 205^\circ C}$ $CaSO_4 \cdot 2H_2O$ $\xrightarrow{\Delta ,\, 120^\circ C}$ $X$. $X$ and $Y$ are respectively

Match List-$I$ with List-$II$:

List-$I$	List-$II$
$a$. $Be$	$i$. Treatment of cancer
$b$. $Mg$	$ii$. Extraction of metals
$c$. $Ca$	$iii$. Incendiary bombs and signals
$d$. $Ra$	$iv$. Windows of $X$-ray tubes
