D) A parallelogram has exactly one pair of parallel opposite sides and a kite has no parallel sides.

Someone please help me, Ive tried and now I need help ._.

for the first question: B) Diagonals bisect each other.

We know that diagonals are perpendicular on square but not on a parallelogram

for the second question: Can't seem to remember properties of rhombus, so i'll refrain from making an assumption.

for the third question: A) A parallelogram and a kite have opposite pairs of sides parallel.
A kite is not a square so its adjacent sides are not congruent. Unless the question tells you that a kite is a square.

first of all, is your name a Shugo chara reference?

secondly, what are the other two options for the first question?
the other 2 questions are D and A
