Task: Answer the multiple choice question.
Query: Which drug exhibits a 15.403\% 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) CCCN(CCC)c1nc(N)c(C#N)c(CC#N)c1C#N
b) COc1cc(C(c2c(C)[nH][nH]c2=O)c2c(C)[nH][nH]c2=O)ccc1OCc1ccc([N+](=O)[O-])cc1
c) O=C(O)Cc1ccc(NC(=O)c2ccc(Cl)c(Cl)c2)cc1
d) Cc1ccc(NC(=O)NC(=O)N(C2CCCCC2)S(=O)(=O)c2ccccc2)cc1
Answer: b. COc1cc(C(c2c(C)[nH][nH]c2=O)c2c(C)[nH][nH]c2=O)ccc1OCc1ccc([N+](=O)[O-])cc1
