**Correct option: (c) 50**

**Explanation:**

4 lines are mutually intersects in ^{4}C_{2} = 6 points.

4 circles are mutually intersects in ^{4}P_{2} = 12 points.

also each line intersect each circle in two points.

**∴** each line intersect 4 circles in 8 points.

∴ Number of points of intersection of 4 lines 4 x 8 = 32

∴ Total intersecting lines = 6 + 12 + 32 = 50
