Explanation:

Let’s break this down. The underlined word is “normality,” which just means things being usual, ordinary, or as expected.

- Option 1: Business as usual

This is basically a synonym—means everything is normal.

- Option 2: Insanity

Now, this is the direct opposite of normality. Instead of calm and regular, it’s disorder and madness.

This is the correct answer.

- Option 3: Order

Order is pretty close to normality, so this isn’t opposite.

- Option 4: Prevaricate

This means to avoid telling the truth or to be evasive. It isn’t related at all to “normality.”
