Which of the following is not an example of acculturation?

a. a toddler learning the alphabet.

Acculturation is a process of receiving another culture and adapting to it, especially with the loss of the own culture.

In other words, when a person or a group of them acquire a new culture and the individuals of the dominated culture adapt incorporating elements of the dominant culture, forgetting their culture of origin, we are talking about acculturation.

In this context, acculturation may include learning a new language, immersion, assimilation, and integration, being this considered a step in  transitioning into a new culture.

For example, a man taking a Spanish class is an important factor in his process of assimilating the new culture, as well as, a young girl attending a class on Native American basketry techniques. In addition, a woman researching about Italy before her trip to Venice involves learning information in order to inmerse in a new culture and understand it.

Therefore, the only option that is not an example of this described situation is:

Because, in this case it may refer to learning the alphabet of his or her mother language, hence its own culture.
