not sure? get a hint: 50/50

Explanation:

A wedge is a simple machine that is thick at one end and tapers to a thin edge at the other end. Its cross - section is triangular.

• The second option “a small and inadequate amount” is not related to the meaning of “wedge”.
• The third option “lawfulness by virtue of being authorized” is about legality and has no connection with “wedge”.
• The fourth option “lack of physical or intellectual ability or qualifications” is about a person's ability or qualifications and not about the geometric or mechanical concept of a wedge.

Answer:

any shape that is triangular in cross section
