Step 1: Know the law.
This question is about Section 105 of the Bharatiya Nagarik Suraksha Sanhita (BNSS), 2023, which is the new criminal procedure code that replaced the old CrPC.
Step 2: Understand what a search and seizure is.
When police search a place and take away things as evidence, there is always a worry that something could be planted or that the process is unfair. The new law tries to fix this.
Step 3: See the new rule.
Section 105 says the whole search and seizure must be recorded by audio-video electronic means, usually on a mobile phone or camera. This recording is now mandatory.
Step 4: Why this rule helps.
A video record makes it hard for anyone to later claim that evidence was planted or that the search was done wrongly. It brings honesty and transparency to police work.
Step 5: Rule out the wrong options.
A signed confession is not required and would in fact be improper. A Judicial Magistrate need not be present during the search. The law does not demand five local residents as witnesses for this section. So these three do not match Section 105.
Step 6: State the answer.
The mandatory new requirement is recording the search and seizure on audio-video.
\[ \boxed{\text{The documentation of the entire search and seizure process via audio-video electronic recording}} \]
