The following sentence has been split into four segments. Identify the segment that contains a grammatical error.
My dog / barks / very louder / at night.

Correct option is B

Option (b) "very louder" contains an error.
· Error: "Very louder" is incorrect because "louder" is the comparative degree of "loud," and comparative adjectives are not used with "very." Instead, the correct phrase should be "very loud" or simply "louder."
· Correction: The sentence should be "My dog barks very loud at night." OR "My dog barks louder at night."
· Grammatical rule used:
· "Very" is used with adjectives in the positive degree ( very strong, very big, very loud).
· For comparative adjectives, "much" is used instead of "very" ( much louder, much stronger).
Example:
❌ She speaks very louder than me. (Incorrect)
✅ She speaks much louder than me. (Correct)
