B - they have the same suffix (al) meaining a kind or form.

None of them have a prefix (at the beginning of the word), they do not have similiar meanings and they have different root words.

Answer 2

They have the same suffix.

Step-by-step explanation:

Suffixes are elements (singly insignificant) that, added to a radical, form a new word. Its main feature is the grammatical class change that generally operates. In the case of the words "partial", "palatial" and "potential", the suffix "al" added to the radical causes a change in the grammatical class of these words.
