a

Explanation:

Analyze the child's speech errors

The child uses "breaked" instead of "broke" and "runned" instead of "ran."

Identify the underlying linguistic process

These errors occur when a child applies standard grammatical rules (like adding "-ed" for past tense) to irregular verbs that do not follow these rules.

Match with the correct psychological term

This grammatical error is known as overregularization (or overgeneralization).

Answer:

• A. overextension
• B. telegraphic speech
• C. overregularization (Correct answer)
• D. fast mapping
