The correct answer is D. An absolute construction
Explanation:
An absolute construction is a type of grammatical construction that is not directly linked to the rest of the elements of the sentence it belongs, this implies an absolute construction is related to a sentence, but not connected grammatically to it and therefore without the absolute construction the sentence expresses a complete idea, in this way "Weather permitting" is the absolute construction as it is not grammatically connected to the sentence. Additionally, most absolute constructions are composed of a noun or substantive, which in this case is "weather" and a participle (-ing word used as adjective or noun), which in this case is "permitting".Thus, this sentence begins with an absolute construction as "weather permitting" is not grammatically linked to the rest of the sentence and it follows a substantive participle construction and both features are related to the concept and characteristics of absolute construction.
