Task: Answer the multiple-choice question.
Question: Which drug exhibits a -1.825\% 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, or c without using any other words.
Options:
[a] O=S(=O)(c1ccc2oc(SCc3cn4ccsc4n3)nc2c1)N1CCOCC1
[b] O=C(NCc1ccco1)c1cc(-c2ccncc2)nc2ccccc12
[c] COc1ccc(C2Nc3ccccc3C(=O)N2NS(=O)(=O)c2ccccc2)c(OC)c1
Answer: a. O=S(=O)(c1ccc2oc(SCc3cn4ccsc4n3)nc2c1)N1CCOCC1
