Task: Answer the multiple-choice question.
Question: Which drug has a -18.963\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a.) O=C(CSc1nc2ccccc2s1)NC1CCCC1
b.) O=S(=O)(c1ccc2c(c1)nc(COc1ccc(Cl)cc1)n2CC1CCCO1)N1CCOCC1
c.) Cc1cc(C)cc(NS(=O)(=O)c2ccc(NC(=S)Nc3ccccc3)cc2)c1
Answer: b. O=S(=O)(c1ccc2c(c1)nc(COc1ccc(Cl)cc1)n2CC1CCCO1)N1CCOCC1
