Find the polynomial function from zeros -1 and 1 - 3i

You should put in order first
{2.7,9.2,10.9,11.2,12.5,13.6,19.9}
Maximun and mininm are logic

The first quartile, Q1, is the value at or below which approximately a quarter (25%) of all the values ​​of the sequence (ordered) remains; The second quartile Q2 is the value below which 50% of the data remains (Median), the third quartile Q3 is the value below which the three quarters remain ...

So I see answer B and C are the same
