Through my research I found questions similar to this and found answers that match.
A. The traits I admire most in a person are being honest, being courageous, and compassionate. B. The traits I admire most in a person are honesty, courage, and compassion. C. The traits I admire most in a person are being honest, courage, and compassion. D. The traits I admire most in a person are that he is honest, is courageous, and compassionate.
Among those choices, the best answer would be letter choice B) or the second option.
Answer: The traits I admire most in a person are honesty, courage, and compassion.
The last three elements of the sentence do not match in structure. "Honesty" and "courage" are nouns that name character traits and stand on their own. "Being compassionate," however, requires a gerund (-ing ending) to function as a noun. This last characteristic needs to be changed to "compassion" in order to achieve parallel structure in the sentence.
