Answer:
D.) only lines p, q and r
Explanation:
(all of them are parallel)
If this was a multiple choice question then yes, it is choice "only lines p, q, and r" are parallel. Regardless of the angle, the three lines that intersect line t must be parallel to each other, but they cannot be parallel to the line they intersect. This means only lines p, q, and r must be parallel to each other.
