Shooting someone "for breaking into [one's] house"? Be very careful! The citizen may use deadly force to defend himself and his family, and in Texas, to protect property under some circumstances, but no citizen can lawfully use deadly force because someone has committed a crime, without due process.
The laws depend on the state. I live in NC, and there is no "Duty to Retreat" and force is allowed to prevent the
forcible entry itself, not to mention what happens once entry is gained and you are in fear for your family and your own lives.
Frankly, I cannot imagine there being any good and friendly reason that someone is smashing through a door or window. (Aside from LE performing their duties)
N.C. Gen. Stat. Sec. 14-51.1
§ 14‑51.1. Use of deadly physical force against an intruder.
(a) A lawful occupant within a home or other place of residence is justified in using any degree of force that the occupant reasonably believes is necessary, including deadly force, against an intruder to prevent a forcible entry into the home or residence or to terminate the intruder's unlawful entry (i) if the occupant reasonably apprehends that the intruder may kill or inflict serious bodily harm to the occupant or others in the home or residence, or (ii) if the occupant reasonably believes that the intruder intends to commit a felony in the home or residence.
(b) A lawful occupant within a home or other place of residence does not have a duty to retreat from an intruder in the circumstances described in this section.
(c) This section is not intended to repeal, expand, or limit any other defense that may exist under the common law. (1993 (Reg. Sess., 1994), c. 673, s. 1.)
EDIT: To answer the OP, it would really be situational for me and my wife. If it was certainly someone "inside the home," I would say A or C.
I live in a very rural mountain area with some fenced and gated acreage, and keep 3 dogs inside the home. Dogs are a great defense, but can give you false warnings. Often times, the dogs are up and barking at night, it might be a raccoon, possum, bobcat, or wandering bear. It's not inside my home, but I do want to know what is outside. Spotlights, not 911 and hide. It may be someone broken down, or wrecked, needing help - this has happened several times - bad mountain road.
If it is a home invasion, they are coming to you, let them pass through the funnel. If it's a burglar, I am not letting them walk away with whatever they want. Dogs would be the first line of defense, while grabbing a light and something better than a sharp stick, while the wife has the phone and her own something better than a sharp stick.
