Find the part of the given sentence that has an error in it. If there is no error, choose 'No error'.
The toad lay in her lap breathing heavy.

Correct option is D

Option (d) contains an error.
Explanation: The phrase "breathing heavy" is incorrect because "heavy" is an adjective, and it should not be used to describe the verb "breathing." The correct adverbial form "heavily" should be used to modify the verb "breathing." Adverbs describe how an action (verb) is performed. Therefore, the correct sentence should be "breathing heavily."
Corrected sentence: The toad lay in her lap breathing heavily.
Grammatical rule used: Adverbs modify verbs, adjectives, or other adverbs. When describing how an action is performed, the adverb form should be used. For example: He spoke softly (not "soft").
