Option A covers these values, as it tests the boundary values of 0, 20, and 40 square yards, as well as the values that are one square yard more or less than these boundaries. It also tests the maximum possible value for the carpet area and the value that exceeds it. The other options do not test all the boundary values or have redundant values. References =
