The locomotor-genital conflict (age 3-5) involves

A) initiative versus guilt.
B) identity versus role confusion.
C) autonomy versus doubt and shame.
D) trust versus mistrust.

The locomotor-genital conflict is part of Erik Erikson's theory of psychosocial development and occurs during the early childhood stage (ages 3-5 years). At this stage, children are experiencing conflict between their sexual instincts (genital) and their desire for physical exploration and mastery (locomotor). This conflict can result in feelings of guilt and shame if not resolved, which fits with the initiative versus guilt conflict in Erikson's theory. Therefore, the best choice is A) initiative versus guilt.
