Select the option that expresses the given sentence in direct speech.

The young girl asked her father where she could keep her new bicycle.

The correct answer is: The young girl said to her father, “Where can I keep my new bicycle?”

Step-by-step Explanation:
To convert the given sentence from indirect speech to direct speech, follow these rules:
1. Reporting Verb: The indirect reporting verb phrase "asked her father" changes to "said to her father" when introducing direct speech containing an interrogative sentence.
2. Pronouns: In indirect speech, the pronoun "she" and possessive adjective "her" refer to the subject ("the young girl"). In direct speech, these change to first-person form: "she" becomes "I" and "her" becomes "my".
3. Tense of the Modal Verb: The past tense modal verb "could" in indirect speech changes back to the present tense modal verb "can" in direct speech.
4. Sentence Structure and Punctuation: The indirect clause structure ("where she could keep") converts back to inverted interrogative structure ("Where can I keep...?"), enclosed in quotation marks with proper capitalization and a question mark.

Combining all these steps gives the correct direct speech sentence:
The young girl said to her father, “Where can I keep my new bicycle?”
