Task: Answer the multiple choice question.
Question: Which drug has a -1.675\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a) CCCCN(C(=O)c1ccc(N2CCCC2=O)cc1)c1c(N)n(CCC)c(=O)[nH]c1=O
b) CCCCNC(=S)NNC(=O)c1ccoc1C
c) Oc1ccccc1C=Nc1ccccc1-c1nc2ccccc2[nH]1
d) O=c1c2ccccc2nc2sc(Nc3cccc(Cl)c3)nn12
Answer: b. CCCCNC(=S)NNC(=O)c1ccoc1C
