Final answer:
C) Abilities 1 and 2, related to diagnosing, recognizing, and controlling emotions, are included in the author's definition of emotional intelligence, thus making option C the most accurate answer.
Step-by-step explanation:
The question asks which abilities related to emotional intelligence are included in the author's definition. Based on the given reference to Parker, Saklofske, & Stough (2009) and Daniel Goleman's definition, abilities related to diagnosing and recognizing emotions, controlling emotions, and managing oneself with self-confidence are typically included within the concept of emotional intelligence.
Consequently, options 1, 2, and 4 pertain to emotional intelligence as they are about understanding and regulating one's emotions and handling them with confidence. Ability 3, which is the ability to lead a team, is more of a social skill that can be an outcome or application of having a high emotional intelligence, but not a core component defined by the authors in their basic definition of emotional intelligence. Therefore, the most accurate answer, given the possible options and the information provided, would be C) Abilities 1 and 2 are included in the author's definition.
