Task: Answer the multiple choice question.
Question: Which drug exhibits a 12.966% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a COCCn1c(SCC(=O)OCc2ccccc2)nc2c1c(=O)[nH]c(=O)n2C
b Cc1ccccc1-n1c(SCC(=O)N/N=C/c2c(C)nn(-c3ccccc3)c2C)nc2ccccc2c1=O
c C=CCc1cc(/C=C/c2nc(O)c([N+](=O)[O-])c(=O)[nH]2)cc(OC)c1O
d CC(C)CN(C(=O)COC(=O)c1ccc(Br)o1)c1c(N)n(Cc2ccccc2)c(=O)[nH]c1=O
Answer: d. CC(C)CN(C(=O)COC(=O)c1ccc(Br)o1)c1c(N)n(Cc2ccccc2)c(=O)[nH]c1=O
