Claire thinks that if she draws a parallelogram with 2 congruent sides, it must be a rhombus. jacob thinks that she would need to draw a parallelogram with at least 3 congruent sides before she could be sure it was a rhombus. who is correct, if anyone, and why?

a: only claire is correct, because if the figure is a parallelogram and 2 sides are congruent, it must have all 4 sides congruent.

b: only jacob is correct, because a parallelogram with 4 congruent sides must have 2 pairs of opposite sides that are congruent.

c: both are correct because if a figure has at least 2 congruent sides, it must have 4 congruent sides.

d: neither is correct because one would need to draw 4 congruent sides in order to be sure the figure was a rhombus
