Problem statement: Answer the multiple choice question.
Query: Which drug has a 16.239\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a O=C(Nc1ccc(-n2ccnc2P(=O)(O)c2ccccc2)cc1)c1ccccc1Br
b O=C(CNC(=S)N(Cc1ccc(F)cc1)C1CCCCC1)NC1CC1
c O=C(NNC(=O)c1ccc([N+](=O)[O-])cc1)c1ccc(Br)cc1
d Cn1nc(C(=O)Nc2cccc(C(F)(F)F)c2)ccc1=O
Answer: c. O=C(NNC(=O)c1ccc([N+](=O)[O-])cc1)c1ccc(Br)cc1
