Which sentence has a gerund functioning as the object of a preposition? options: a.)they us exuberantly for meeting with them to discuss the deal. b.)driving delights me when i take off spontaneously for random destinations. c.)with all these poems to learn, i need to start memorizing them immediately. d.)while i enjoy biking in the woods, i prefer the placid setting by the lake.

The sentence that has a gerund functioning as the object of a preposition is A: "They thanked us exuberantly for meeting with them to discuss the deal".

Words that are formed from verbs but do not act as verbs are called verbals. This is the case of gerunds since they are formed from verbs but act as nouns.   Therefore, they behave as subjects, direct objects, objects of prepositions, predicate nouns, and more.

In this case, the gerund is "meeting". It functions as the object of the preposition "for" and it also takes complements and modifiers ("meeting with them to discuss the deal").

a complex sentence consists of an independent clause and one or more dependent clauses.  

to write complex sentences, we must use subordinating conjunctions.  

all the complex sentences begin with a subordinating conjunction and when it occurs, a comma must be place at the end of the dependent clause. on the contrary, if the sentence begins with an independent clause, then no comma is used.
