Answer is E. A square is both a rectangle and a rhombus.

15 rectangles, 10 rhombus, 8 squares.
Subtract # of squares from the number or rectangles and number of rhombus

15-8 = 7 (Number of cards that are rectangles but are not squares)
10-8 = 2 (Number of cards that are rhombuses but are not squares)
7+2+8 = 17 cards. 30-17 =13 possible cards as circles.
