The area of central circle would be : pi. d^2 /4
the area of the next region would be : pi ( d^2 - d^2/4) = 3/4 pi d^2
The outermost region would be : pi (9d^2 / 4 - d^2/4) = 5/4 pi d^2
Just multiply all equation with 4, you will get that the ratio will become 1 : 3 : 5
Hope this helps
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.
