Solution

The correct option is C $5$
$2 B$
x $6$
__
$1 B 0$

The multiplication of $B$ and $6$ is giving $0$ i.e., $B \times 6 = 0$
The above condition is possible only when digit $B$ is $5$ , because $5 \times 6 = 30$ .
Ones digit will be $0$ . $3$ will be carry for the next step to get the value as $15$ .
Therefore, the multiplication is as follows:
3
$25$
X $6$

$150$

So, option C is correct.
