The correct answer is B. Yes, because 1 and 4 are congruent.
Alternate interior angles are congruent when two parallel lines are cut by a transversal. Angles 1 and 4 are alternate interior angles, so they are congruent. This means that lines c and d are parallel.
The other answer choices are incorrect.
A. No, because 1 and 5 are not congruent. This is incorrect because alternate interior angles are congruent, not corresponding angles.
C. Yes, because 5 and 8 are congruent. This is incorrect because corresponding angles are congruent, not alternate interior angles.
D. No, because 1 and 5 are not supplementary. This is incorrect because supplementary angles are angles that add up to 180 degrees. Angles 1 and 5 are not supplementary, but this does not mean that lines c and d are not parallel.
Therefore, the answer is B. Yes, because 1 and 4 are congruent.
