Verified step by step guidance

1. Understand the concept of overregularization: It is a language development phenomenon where children apply regular grammatical rules to words that are exceptions. For example, using 'mouses' instead of 'mice'.
2. Identify the grammatical rule being over-applied: In this case, the regular rule for forming plurals in English is to add 's' or 'es' to the end of a word.
3. Examine each option to see if the regular rule is incorrectly applied: 'Two mouses' applies the regular plural rule to an irregular noun, 'mouse', which should be 'mice'.
4. Compare with other options: 'Dogs' correctly applies the plural rule, 'Water bottle red' is a word order error, and 'Angry I’m' is a syntax error, not overregularization.
5. Conclude that 'Two mouses' is the example of overregularization, as it demonstrates the incorrect application of a regular grammatical rule to an irregular case.
