Task: Answer the multiple choice question.
Query: Which drug exhibits a -12.420% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a Cn1cccc1Cc1nnc(SCC(=O)N2CCOCC2)n1-c1ccc(F)cc1
b Br.CCn1c(=N)n(CC(=O)c2ccc(Br)s2)c2ccccc21
c COc1cc([N+](=O)[O-])ccc1NC(=O)CCN1C(=O)C2C3CCC(C3)C2C1=O
d N#Cc1c(-c2ccccc2)c(-c2ccccc2)nn(CC(=O)NNC(=O)Nc2ccc(Cl)c(Cl)c2)c1=O
