Solution

The correct option is C $2$
In the given diagram, the pattern followed is
In first column,
$1^{2} + 3^{2} + 5^{2} = 35$
In second column,
$7^{2} + 3^{2} + 4^{2} = 74$
Therefore, in the third column,
$6^{2} + x^{2} + 8^{2} = 104$
$36 + x^{2} + 64 = 104$
$x^{2} = 4$
$x = 2$
Answer is Option $B .$
