Task: Answer the multiple choice question.
Question: Which drug has a 12.463\% 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, or d without using any other words.
Options:
[a] OC(CNCCc1ccccc1)COc1ccc(OCC(O)CNCCc2ccccc2)cc1
[b] O=S(=O)(NCc1ccccn1)c1cc(Cl)ccc1Cl
[c] O=S(=O)(NCCc1ccc(F)cc1)c1cccc2cccnc12
[d] O=C(Cn1c(=O)oc2ccccc21)NCCc1ccccc1
Answer: b. O=S(=O)(NCc1ccccn1)c1cc(Cl)ccc1Cl
