Answer 4

@VengefulWave
You are correct in considering between 1 and 3.

Answer 5

To get the right answer, you need to know that all the answers are in set notation.

One of the set notations is enclosing \(unique\) elements in braces.
For example, {apple, orange, peach} is a set.
{eggs, milk, eggs, bacon} is an incorrectly represented set because usual conventions of the set notation is not to repeat elements.

I think there is enough for you to find the correct answer.
