a
b
c
d

Explanation:

The mean length of utterance (MLU) is a measure of linguistic productivity in children. It is calculated by dividing the number of morphemes by the number of utterances. MLU increases as children mature (D is true). It is measured in morphemes (B is true). It does refer to the length of spoken statements (C is true). However, it does not track the complexity of syntax usage. Syntax complexity is a different aspect of language development.

Answer:

A. The MLU tracks the complexity of syntax usage.
