Q. Two lines in three dimensional space if not parallel always intersect.

1. True
2. False

Q. Skew lines are non coplanar lines.

1. True
2. False

Q. Equation of the line of shortest distace between the lines $\frac{x}{2}=\frac{y}{-3}=\frac{z}{1}$ and $\frac{x-2}{3}=\frac{y-1}{-5}=\frac{z+2}{5}$ is

1. $3(x-21)=3y-92=3z-32$
2. $\frac{x-\left(\frac{62}{3}\right)}{\frac{1}{3}}=\frac{y-31}{\frac{1}{3}}=\frac{z+\left(\frac{31}{3}\right)}{\frac{1}{3}}$
3. $\frac{x-21}{\frac{1}{3}}=\frac{y-\left(\frac{92}{3}\right)}{\frac{1}{3}}=\frac{z+\left(\frac{32}{3}\right)}{\frac{1}{3}}$
4. $\frac{x-2}{\frac{1}{3}}=\frac{y+3}{\frac{1}{3}}=\frac{z-1}{\frac{1}{3}}$
