Solution

The correct option is C 150 J
According to the question,
Vector Force $F = 2 i + 15 j + 6 k$ Newtons,
where the $i, j, k$ are the unit of the vector along axes.
Where,
$s =$ displacement
$= 10 j$ meters
Work done $(W) = F . s$
$= (2 i + 15 j + 6 k) .10 j$
$= 20 i . j + 150 j . j + 60 k . j$
$= 150 j$
