$$Detailed explanation of why it is correct — include conceptual, or contextual depth.$$

The sentence "Where he lives is not known to anyone" contains the noun clause "Where he lives." Remember, a noun clause is a dependent clause that functions exactly like a noun in a sentence. This means it can act as the subject of the verb, the object of the verb, the object of a preposition, or a complement. In this sentence, the verb of the main clause is "is known." The entire clause "Where he lives" is performing the function of the subject of this verb. If you replace the clause with a simple noun or pronoun (e.g., "His address is not known to anyone"), the sentence retains its grammatical structure and meaning. Since the clause "Where he lives" is performing the role of the subject, it is definitively functioning as a noun clause. Noun clauses are often introduced by subordinating conjunctions such as "that," "what," "where," "why," "how," or "who," but their function, not the introductory word, is what truly defines them. Here, "Where he lives" is indispensable for the sentence to make sense, acting as the subject performing the action (or state of being) described by the verb phrase.

The incorrect option is 1:
The sentence "Wait, until I come" contains the dependent clause "until I come." This clause functions as an adverbial clause of time, modifying the verb "Wait" by indicating *when* the action should stop or continue until. It does not function as a subject, object, or complement, so it cannot be a noun clause.

The incorrect option is 2:
The sentence "Where the piper went the children followed" contains the clause "Where the piper went." While this clause begins with a word typical of noun clauses ("Where"), in this context, the main clause is "the children followed." The dependent clause "Where the piper went" functions as an adverbial clause of place, indicating *where* the children followed. It modifies the verb "followed" and, therefore, is not a noun clause.

The incorrect option is 3:
The sentence "The pen that I bought is lost" contains the clause "that I bought." This clause modifies the noun "pen," specifying which pen is lost. Since it modifies a noun, it functions as an adjectival (or relative) clause, not a noun clause. Adjectival clauses are introduced by relative pronouns like *that*, *which*, or *who*.
