Task: Answer the multiple choice question.
Query: Which drug exhibits a -2.120% 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: COc1ccc(Cl)cc1N1CC(c2nc3ccccc3[nH]2)CC1=O
b: Cc1ccc(Nc2c(-c3ccccn3)nc3cc(C)ccn23)cc1
c: COC(=O)C1=COC(C)C2CN3CCC4(C(=O)Nc5ccccc54)C3CC12
d: O=C(c1ccc(F)cc1)C1CCN(C(=O)c2ccccc2F)CC1
e: CCCCCSc1nc2c(c(=O)[nH]c(=O)n2C)n1C
Answer: e. CCCCCSc1nc2c(c(=O)[nH]c(=O)n2C)n1C
