Task: Answer the MCQ question.
Query: Which drug exhibits a 17.729% 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 additional words.
Options:
a: COc1ccc(S(=O)(=O)N2CCOCC2)cc1Cl
b: Cc1nc2nc(SCC(=O)N3CCOCC3)nn2c(C)c1Cc1ccccc1
c: CCCCNC(=O)C(=O)NC(C)CCc1ccccc1
d: CCSc1nc2c(c(=O)n1Cc1ccccc1)SC(C)C2
e: O=c1cc(CN2CCN(c3cccc(Cl)c3)CC2)c2cc(O)c(-c3ccccc3)cc2o1
Answer: e. O=c1cc(CN2CCN(c3cccc(Cl)c3)CC2)c2cc(O)c(-c3ccccc3)cc2o1
