Since Jonathan enjoys problem-solving and number-related activities a lot, the best learning style that will fit him is (D) mathematical-logical.
The other learning styles might not be that suitable, since bodily/kinesthetic refers to how the individual will learn about body movements better, such as sports and dance, while interpersonal refers to how the individual has a better chance of learning something through communicating with other people. Visual/spatial is also unsuitable since this learning style will be more suitable with someone who prefers to read diagrams or make them.
