Based on the information provided, choose the characteristic that is acquired and cannot be inherited from the options below.

An acquired characteristic is one that develops as a result of environmental factors and cannot be inherited. Therefore, the correct answer to this question is the size of the body. Body size can be influenced by various factors such as diet, exercise, and environmental conditions, which are acquired and can change throughout a person's lifetime. In contrast, eye color, skin color, and hair type are inherited traits that are determined by an individual's genes and passed down from parents.
