In order to form a negation, just add "not" to a statement or take "not" out of a statement if it already exists.
Mnenie [13.5K]

<u>Answer:</u>

The correct answer option for this is: False.

<u>Step-by-step explanation:</u>

We are given the following statement which we are to determine whether its true or false:

<em>In order to form a negation, just add "not" to a statement or take "not" out of a statement if it already exists.</em>

To form a negation, we add the word 'not' to a statement - this part of the given sentence is true.

While 'or take "not" out of a statement if it already exists' is false which makes the whole sentence false.
