A parallel structure means that withing the sentence the same structure/scheme is used everywhere. So the correct answer is B. A cannot be correct as you have "BEING honest", "BEING courageous" and then just "compassionate". BEING was deleted. C is also incorrect as you have "BEING honest" and then just nouns "courage" and "compassion" - the structure has changed. It is the same case with D - "IS honest", "IS courageous" and then just "compassionate", without IS. And B is correct because we have three nouns "honesty", "courage", "compassion" - the structure remains the same.
To be reticent is to not reveal one's thoughts readily. In this case, it is the reticence of the author. The author does not reveal their thoughts readily.
