Task: Answer the multiple-choice question.
Question: Which drug exhibits a -5.534\% 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 O=C(c1ccc(-c2nnc(Nc3ccccc3)c3ccccc23)cc1)N1C[C@H]2C[C@H](C1)c1cccc(=O)n1C2
b O=C(CCS(=O)(=O)Cc1ccccc1)N1CCN(c2ccccc2)CC1
c O=Cc1c(Cl)cccc1Cl
d CSc1nccc(Oc2ccc(C#N)cc2)n1
e O=C(NCc1ccccc1CN1CCCCC1)c1ccccc1N1CCCC1=O
Answer: b. O=C(CCS(=O)(=O)Cc1ccccc1)N1CCN(c2ccccc2)CC1
