Concept:A direct question in direct speech must be enclosed in quotation marks and end with a question mark inside the closing quotes.
Explanation:The given sentence is a direct question because the speaker directly asks, “Will you come to my house?”.
In direct speech, a question must use a question mark at the end, not a comma or an exclamation mark.
Option A uses a comma, which is incorrect for a direct question.
Option B uses an exclamation mark, which is also incorrect because the sentence is asking something, not exclaiming.
Option C correctly places the question mark inside the quotation marks.
Therefore, the correctly punctuated sentence is: “Will you come to my house?” he asked.
Answer:Option C: “Will you come to my house?” he asked.
