Which form of punctuation is best suited for non - restrictive clauses that may include surprising information?

Commas

Dashes

Parenthesis

No punctuation

The best suited punctuation for non-restrictive clauses are commas. The information of the clause can include surprising information.

Examples:

My cat, which loves some vegetables, takes the vegetables from my shopping bag.

2-My teacher, who has tatoes on his bald head, loves teaching arts.

3 - My teacher, who looks very young, is very traditional.

The underlined clauses are examples of non - restrictive clauses. They are between commas because we can omit them. If we take them out, the main clauses have meaning, anyway. The information in the non-restrictive clauses can be surprising - look at examples 1 and 2 above -, or not - look at example 3.

The answer would be D or last choice.
