I would choose the last choice, D. Adverbial.
Adverbial phrases include two or more words that serve as adverbs. So "in an hour or two" can be classified as an adverb phrase.
.Answer:
<em>Direct object</em>
Explanation:
A gerund phrase (<em>scrubbing with stain remover</em>) is a type of phrase where the main word is a gerund (verb root + -ing). Gerund phrase always serves as a noun and that noun can have the function of a subject, indirect or direct object, predicate nominatives or object of a preposition.
In the given sentence the gerund phrase functions as a direct object where the noun (in this case gerund phrase - <em>scrubbing with stain remover</em>) is receiving the action of the verb<em> tried.</em>
