10 points

To determine the correct answer, let's examine each option and consider how it relates to Kohlberg's theory of moral development.

a. Males are best suited to this.
This option suggests that only males are capable of abstract ethical thinking according to Kohlberg's theory. However, Kohlberg's theory does not propose a gender-specific aspect to moral development. Therefore, this option is not aligned with Kohlberg's theory.

b. Males and females with higher education are best suited to this.
This option suggests that individuals with higher education, regardless of gender, are best suited for abstract ethical thinking. Kohlberg's theory does suggest that individuals who have been exposed to moral philosophy and ethical principles are more likely to reach higher stages of moral development. Therefore, this option aligns with Kohlberg's theory.

c. Females are capable of achieving abstract ethical thinking.
This option suggests that females are capable of achieving abstract ethical thinking. Kohlberg's theory does not propose any gender-specific limitations to moral development. Therefore, this option aligns with Kohlberg's theory.

d. Males and females with military service are best suited to this.
This option suggests that individuals with military service are best suited for abstract ethical thinking. While military service may expose individuals to challenging ethical situations, it does not necessarily correlate with higher stages of moral development. Therefore, this option is not aligned with Kohlberg's theory.

Based on the above analysis, the options that align with Kohlberg's theory of moral development are:
b. Males and females with higher education are best suited to this.
c. Females are capable of achieving abstract ethical thinking.

Therefore, the correct answer is either b or c, depending on the specifics of Kohlberg's theory. Further examination or research may be needed to determine which answer is more accurate.
