After conducting research on personality traits for many years. Professor Torres concludes that traits can be described in terms of five basic factors. Professor Torres agrees with the trait model proposed by: a. Hans Eysenck b. Hermann Rorschach c. Paul costa, Jr. and Robert McCrae d. Raymond Cattell

The multiple choice question is asking which personality theorist is associated with the concept that traits can be described using five basic factors. It's important to understand the different propositions each theorist made. Once that is understood, it will be easier to answer the question.

a. Hans Eysenck: Eysenck proposed a model which consists of three dimensions of personality (Extraversion, Neuroticism, and Psychoticism). This doesn't fit the five-factor model the question asks for. b. Hermann Rorschach: Rorschach developed the projective psychological test known as the Rorschach inkblot test. This is not a trait theories model, so this doesn’t fit our question. c. Paul Costa, Jr. and Robert McCrae: Costa and McCrae developed the five-factor model, also known as the "Big Five" model of personality traits. This model includes the dimensions of extraversion, agreeableness, conscientiousness, neuroticism, and openness to experience. This is consistent with the question's description. d. Raymond Cattell: Cattell developed a 16 factor theory of personality, which is different from the five-factor model which is asked in the question.

From the analysis of all these personalities and their theories, it can be concluded that Professor Torres agrees with the trait model proposed by Paul Costa, Jr. and Robert McCrae, as mentioned in the option (c). Therefore, (c) is the correct answer.
