Task: Answer the multiple-choice question.
Question: Which drug exhibits a -2.769\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a COc1ccc(C(CNC(=O)Cc2ccccc2F)N2CCCCC2)cc1
b COc1cccc(Nc2nc(-c3sc(NC(=O)c4ccco4)nc3C)cs2)c1
c O=C(Oc1ccc2ccccc2c1Cl)N1CCCC1
d CCCN(CC1CC1)C(=S)Nc1ccc(Oc2ccccc2)cc1
e COCCOC(=O)C1=C(N)Oc2c(c(=O)oc3ccccc23)[C@@]12C(=O)Nc1ccccc12
Answer: a. COc1ccc(C(CNC(=O)Cc2ccccc2F)N2CCCCC2)cc1
