Which of the following statements regarding verbal ability and gender is incorrect?

A) females outscore males on verbal tasks on college entrance tests
B) girls outperform boys on reaching achievement tests throughout school years
C) spelling is a strength for girls as compared to boys
D) boys are weaker at writing than girls

The statement that females outscore males on verbal tasks on college entrance tests is incorrect because while there are observed differences in verbal abilities between genders, these differences are not consistent across all types of tests or populations. Studies have shown variability in performance, and it's not accurate to generalize that females always outscore males on verbal tasks in college entrance exams.
