Projective personality assessments are:

A) Structured
B) Helpful
C) Unstructured
D) Unhelpful

Projective personality assessments are unstructured tests that rely on individuals' responses to ambiguous stimuli such as inkblots, pictures, and incomplete sentences. While these tests can provide insight into individuals' thoughts and emotions, they are also highly subjective and may not have strong scientific evidence supporting their validity and reliability. Therefore, they are considered unstructured and may not be as helpful as other types of personality assessments.
