Despite the great interest in the Loch Ness monster, it is highly unlikely that such an animal actually exists. Which sentence from the passage best supports this conclusion?
A “Whether the creature really exists or not has been a matter of great debate for decades.”
B “Some people who believe in Nessie say that she’s made her home in the region for more
than a thousand years.”
C “Since the 1930s, dozens of serious, scientific searches have been undertaken to find the
Loch Ness monster.”
D “Many animals whose existence we take for granted today might once have been
considered cryptids.”

Hmm I say A

Explanation:

I say A since when writing your conclusion you are summarying what your writing is about. I feel as C would work good as a paragarph itself as eveidenc o support a claim stating that the Loch Ness mosnter isn't real. A instead of trying to state something spescfic it summarizes syaing whether ot not if the moster is real

- "a nonrestrictive clause functions as a modifier to a noun (that is an object, person or concept). these clauses can be described by the following three options: it is set off by comas, it contains a subject and a verbs and it adds nonessential information to the sentence.

for example, in "here is bill gates, who confounded microsoft software company" we can identify "who confounded microsoft software company" as a nonrestrictive clause modifying the noun bill gates. this clause can be describes as a nonrestrictive clause because it is separated by a comma, it adds nonessential information to identify who bill gates is and it must contain both a subject (who) and a verb (confounded)."
