Task: Answer the multiple choice question.
Question: Which drug exhibits a -0.535\% 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) S=C(NCCc1ccccc1)N/N=C/c1ccccc1Cl
b) CCCc1nn2c(=O)cc(COc3cccc(NC(=O)c4ccco4)c3)nc2s1
c) CCOC(=O)c1[nH]c2ccc(Br)cc2c1NC(=O)CCN1CCOCC1
Answer: b. CCCc1nn2c(=O)cc(COc3cccc(NC(=O)c4ccco4)c3)nc2s1
