The behavior described is known as the A-not-B error, which occurs as babies approach age 1. This is a normal part of development as they are still developing their understanding of object permanence. Option A is unlikely as this behavior is not indicative of a psychological problem. Option B is incorrect as the A-not-B error does not occur before 6 months of age. Option D is incorrect as object permanence is typically developed by the age of 2.
