To determine the correct usage of the word "Absturb," we must first understand its meaning. However, "absturb" appears to be a misspelling or a non-standard word in English, as it does not exist in the dictionary. Therefore, its meaning is unrecognized, and we cannot properly analyze its usage. Let's evaluate each option:
- The explanation he gave was completely absturb.
This sentence uses "absturb" as an adjective, but without a clear meaning, its use is incorrect. - She absturb the offer politely.
Here, "absturb" is used as a verb, which also does not make sense given the lack of definition. - He absturb to the committee's view.
In this sentence, "absturb" seems incorrectly used within the context, and does not convey an understandable action or agreement. - None of the above.
As "absturb" is not a valid English word, none of the sentences use it correctly.
Therefore, the correct answer is: None of the above.
