B. adverb clause
Only one of the sentences contain an adverbial clause. I lay out the explanations below.
<span>(A) NO ADVERBIAL CLAUSE. "Where I could get some coffee" is part of a reported speech. </span>
<span>(B) NO ADVERBIAL CLAUSE. "What she pointed out" is a noun clause. </span>
(C) NO ADVERBIAL CLAUSE. "How to invest my money" is the direct object of know; hence, it's a noun clause.
<span>(D) </span>"Where they can find food easily"<span> is an example of an adverbial clause. It is an adverb of place, answering the question: Where do most animals thrive?</span>
The gerund phrase in the given sentence would be: Training show dogs. This gerund phrase is used as the direct object. The answer is option B. A gerund is a word that ends in -ing, but functions as a noun. A gerund phrase consists of the gerund plus other words that modifies.
