なんじ

いま とうきょう は なんじ ですか。

The correct answer is `なんじ` (nanji). This interrogative word means "what time." It correctly precedes `ですか` (desu ka), which forms a polite question. So, `なんじですか` means "What time is it?" This fits to ask about the time in Tokyo. `とうきょう` (Tokyo) is the topic and should precede `は`. `は` is the topic particle and should come after `とうきょう`. `ですか` is the polite question ending and is already correctly placed at the end of the sentence. *Grammar Tip:* To ask "What time is it (in a specific place)?", the structure is: [Place] + `は` + `なんじですか`?

正解は「なんじ」。「何時ですか」で丁寧な質問文に。「とうきょう」は「は」の前。「は」は助詞。「ですか」は文末。 文法：「～は何時ですか」で時間を尋ねる。
