Answer 1

Did you read the book? its pretty easily found in the text.

a) Macbeth becomes king because he Kills Duncan.

b) Banquo is murdered, but his son escapes so he has a chance to be king in the future.

c) Macduff who Kills Macbeth was not technically born of a women, he was ripped from his mothers womb prematurely (c-section).

d) The army that attacks Macbeth's castle does this by cutting down branches (brinam wood) and hiding behind them while moving closing to hunsinane hill.

You should really try reading the book, its pretty good.

Prophecy
Prophecy sets Macbeth’s plot in motion—namely, the witches’ prophecy that Macbeth will become first thane of Cawdor and then king. The weird sisters make a number of other prophecies: they tell us that Banquo’s heirs will be kings, that Macbeth should beware Macduff, that Macbeth is safe till Birnam Wood comes to Dunsinane, and that no man born of woman can harm Macbeth. Save for the prophecy about Banquo’s heirs, all of these predictions are fulfilled within the course of the play. Still, it is left deliberately ambiguous whether some of them are self-fulfilling—for example, whether Macbeth wills himself to be king or is fated to be king. Additionally, as the Birnam Wood and “born of woman” prophecies make clear, the prophecies must be interpreted as riddles, since they do not always mean what they seem to mean.
