Parallelogram
A rectangle is defined as "a parallelogram with one right angle" A parallelogram is defined as "a quadrilateral with opposite sides equal and parallel" This makes a rectangle a sort of second-generation quadrilateral!
It is a rhombus or a parallelogram
parallelogram with one diagonal
parallelogram in general, and a rhombus also, which is a type of parallelogram

No , a parallelogram can not have a 90 Degree angle .Reason : A Parallelogram can be defined as a quadrilateral whose two s sides are parallel to each other and all the four angles at the vertices are not 90 degrees or right angles, then the quadrilateral is called a parallelogram.
A rhombus, or a square if there is a 90o angle.
A rectangle is defined as "a parallelogram with one right angle" A parallelogram is defined as "a quadrilateral with opposite sides equal and parallel" This makes a rectangle a sort of second-generation quadrilateral!
A rectangle is a parallellogram with one right angle; A parallelogram is a quadrilateral with opposite sides equal and parallel.
none of these are correct
-- Rhombus -- Regular parallelogram
parallelogram with one diagonal
It is a rhombus or a parallelogram
No because it could be an irregular quadrilateral that includes a right angle. A rectangle has four right angles.Yes, a parallelogram with a right angle is always a rectangle. In fact, in my geometry book, some 55 years ago, such was the definition of rectangle.A parallelogram with one right angle will always have four right angles.It is true that you can draw an irregular quadrilateral with a right angle which is not a rectangle but the figure will not be a parallelogram.
