Four objects are being tested to see how they are affected by fluid friction. Object W has a surface area of 4.5 cm2, Object X has a surface area of 2.5 cm2, Object Y has a surface area of 6.2 cm2, and Object Z has a surface area of 3 cm2.

Greater surface area generally creates more fluid friction because more of the object interacts with the fluid. Object Y has the largest surface area, 6.2 cm², so it would be affected most by fluid friction. The correct choice is Y.
