Correct answer: (C) 10
Explanation
The diagonal lines form a rotated 2-by-2 rectangular grid. Choosing two of three lines in each perpendicular family gives 3×3=9 rotated rectangles, including its four small cells. The exterior square adds one axis-aligned rectangle; there are no internal horizontal/vertical lines. Total=**10, C**.
