The sets of numbers given in the alternatives are represented by two classes of alphabets as in the two given matrices. The columns and rows of matrix $I$ are numbered from $0$ to $4$ and that of matrix $II$ from $5$ to $9$. $A$ letter from these matrices can be represented first by its row and next by column number in the matrices. For example,$A$ can be represented by $13, 23$ etc. $T$ can be represented by $58, 65$ etc. Similarly,you have to identify the set for the word "$COLD$".
Matrix $I$

	$0$	$1$	$2$	$3$	$4$
$0$	$D$	$K$	$A$	$E$	$C$
$1$	$C$	$D$	$K$	$A$	$E$
$2$	$K$	$C$	$E$	$A$	$D$
$3$	$K$	$C$	$D$	$E$	$A$
$4$	$E$	$D$	$A$	$K$	$C$

Matrix $II$

	$5$	$6$	$7$	$8$	$9$
$5$	$P$	$L$	$O$	$T$	$N$
$6$	$T$	$P$	$N$	$L$	$O$
$7$	$P$	$N$	$T$	$O$	$L$
$8$	$O$	$N$	$T$	$P$	$L$
$9$	$L$	$O$	$P$	$N$	$T$
