Answer:
The correct answer is indeed letter B) Accepting the award, Marla wanted to thank everyone.
Step-by-step explanation:
In the sentence "Accepting the award, Marla wanted to thank everyone", we have the present participle "accepting". The present participle is formed by adding -ing to a verb. It can function as an adjective - and as the initiator of an adjective phrase or clause, as is the case here - or as a part of a continuous tense. We also have an infinitive functioning as the object of the verb wanted. What did Marla want? To thank. To thank is an infinitive, a verb in its base form.
