a
x−31=y−62=z−23
b
x−11=y−20=z−2−3
c
x−11=y2=z+32
d
x1=y2=z2

detailed solution

Correct option is C

The equation of the line passing through the point  x1,y1,z1and parallel to the line whose direction ratios are a,b,c isx−x1a=y−y1b=z−z1cHere the given point is  1,0,−3and the direction ratios are1,2,2Therefore, the equation of the required line is x−11=y2=z+32
