The correct answer is: x+1-1=y-22=z-55

We know that two lines x-x1a1=y-y1b1=z-z1c1 and x-x2a2=y-y2b2=z-z2c2 are coplanar if x2-x1y2-y1z2-z1a1b1c1a2b2c2=0

Let us verify this option.

The given lines are x+3-3=y-11=z-55 and x+1-1=y-22=z-55.

=-1--32-15-5-315-125

=210-315-125

=25-10-1-15--5+0

=2-5+10=0

Therefore, this is the correct option.
