Question

In the diagram, the only figure that could be parallel to line c is ?

Answer 1

I believe your answer would be line D.

Answer 2

Answer-

Line d could be parallel to line c.

Solution-

In the given picture, there are 4 lines. Two are on the R plane and 2 are on the Q plane.

Line c and d are on R plane, a and b are on Q plane.

Parallel lines are those lines on a plane which do not meet. Two lines on a plane that do not intersect or touch each other at any point are said to be parallel.

So line a and b are not parallel to c.

Actually c and b are intersecting lines, c and a are skew lines.

As c and d are on a single plane and they don't intersect, so they could be parallel to each other.
