All _____ may be used for entry to execute a search warrant.

The use of "necessary and reasonable force" aligns with lawful entry to execute a search warrant. This principle is grounded in the legal doctrine that law enforcement or security personnel must use only the force that is appropriate to facilitate their entry while ensuring the safety of all parties involved.

In situations where a search warrant is being executed, officers are permitted to use enough force to overcome resistance or barriers to their entry. However, this force must be deemed reasonable and necessary given the circumstances. The rationale here is to balance the need for effective law enforcement with the rights of individuals, ensuring that actions taken are justified and proportionate.

While the other options mention different types of force, they do not apply here. Deadly force is only permissible in extreme situations involving an imminent threat to life. Non-lethal force, while often acceptable, does not encompass the full scope of what might be necessary in executing a search warrant. Thus, "necessary and reasonable force" is the most appropriate and legally sound choice for entry in the context of executing a search warrant.
