The correct answer is option 3: either (A) or (B).

Key Points:

• Direct a local investigation to be made by such person as he thinks fit: This gives the Magistrate the discretion to appoint a competent person to investigate locally, gathering necessary information and evidence pertinent to the case at hand under Section 137 or Section 138 of the Criminal Procedure Code (Cr. P.C.).
• Summon and examine an expert: The Magistrate also has the authority to summon experts whose testimony can provide critical insights into specific aspects of the inquiry, thereby aiding in a more comprehensive understanding and resolution of the matter.
• These powers ensure that Magistrates are equipped with the necessary tools to conduct thorough and effective inquiries into disputes or matters requiring judicial attention.
