Task: Answer the multiple choice question.
Question: Which compound has a 9.458\% 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 additional words.
Options:
a) O=C(Nc1ccc(OC(F)F)cc1)c1ccccn1
b) Cn1c(CNS(=O)(=O)c2ccc(Br)cc2)n[nH]c1=S
c) O=C(CCNc1n[nH]c(=O)[nH]c1=O)N/N=C/c1ccc(Cl)cc1
d) COc1cc([N+](=O)[O-])ccc1NC(=S)NCc1ccccn1
Answer: a. O=C(Nc1ccc(OC(F)F)cc1)c1ccccn1
