です

あにの くるまは あたらしくて、とても おおきい です ね。

The correct answer is `です` (desu). This is the polite copula (a form of "to be"). It correctly follows the i-adjective `おおきい` (big) to make the phrase `おおきいです` polite. The sentence then ends with `ね` (isn't it?), forming `とてもおおきいですね` (it's very big, isn't it?). `とても` (very) is an adverb and modifies `おおきい` before it. `おおきい` is the adjective itself, it belongs before `です`. `ね` is the final particle, which comes after `です`. *Grammar Tip:* To make i-adjective sentences polite, simply add `です` after the i-adjective (e.g., `おいしいです` - it's delicious).

正解は「です」。「おおきい」に続き、文を丁寧にします。「とても」は副詞、「おおきい」は形容詞。「ね」は文末助詞で、別の位置。 文法：イ形容詞の後に「です」で丁寧な文。
