Task: Answer the multiple-choice question.
Question: Which drug exhibits a -50.330% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
[a] O=C(COc1ccc(S(=O)(=O)NCc2ccccc2)cc1Cl)NCc1ccccn1
[b] C=CCn1c(SCC(=O)NCc2ccco2)nc2ccccc2c1=O
[c] Cc1cc(OCC(=O)O)n2cc(-c3ccccc3)nc2n1
[d] Cc1cc(C)c(S(=O)(=O)N(C)c2ccccc2)c(C)c1
Answer: b. C=CCn1c(SCC(=O)NCc2ccco2)nc2ccccc2c1=O
