Task: Answer the multiple choice question.
Question: Which compound exhibits a -1.756\% human ether-à-go-go related gene (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 other words.
Options:
a CCCCCCc1ccc(N2C[C@H](Cc3ccccc3)[C@@H](CC(=O)NCc3ccc(OC)cc3)C2=O)cc1
b O=C(Nc1nccs1)c1ccc(-c2ccc(F)c(Cl)c2)o1
c O=C(O)CSCc1c(F)cccc1Cl
d COc1ccc(CNC(=O)C2CCCN2S(=O)(=O)c2ccc(S(=O)(=O)N(C)C)cc2)cc1
e CCN(c1ccccc1)S(=O)(=O)c1ccc2ccccc2c1
Answer: c. O=C(O)CSCc1c(F)cccc1Cl
