Correct Answer: Unambiguous

Solution : The correct choice is the third option .

Unequivocal means leaving no doubt or uncertainty. In this context, unambiguous is a suitable synonym because it also conveys the idea of being clear, definite, and without any ambiguity or confusion.

The meanings of the other words are:

• Articulate : Able to express thoughts and ideas clearly and effectively; well-spoken.
• Complete : Having all necessary or normal parts, components, or steps; entirely finished or whole.
• Doubted : To be uncertain about something; to consider something unlikely or question its validity or truth.

Therefore, the right answer is unambiguous.
