Answer 1

The correct option is A 204

$Squareof1\times 1unit\to 8^2$
$Squareof2\times 2unit\to 7^2$
$Squareof3\times 3unit\to 6^2$
.........................................................
.........................................................

$Squareof7\times 7unit\to 2^2$
$Squareof8\times 8unit\to 1^2$
Total number of square

$=1^2+2^2+3^2+.....+8^2=204$

hence option (a)
