Task: Answer the multiple choice question.
Query: Which compound has a -1.845\% 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 other words.
Options:
[a] O=C(Nc1ccccc1)c1cn(CCBr)cn1
[b] O=C(C1CCCC1)N1CCCC(Nc2ccccc2)C1
[c] Cc1oc(-c2ccc(Cl)cc2)nc1CN1CCCC(C(=O)NC2CC2)C1
[d] CSc1c(C(N)=O)c(-c2ccc(Cl)cc2)nn1C
Answer: b. O=C(C1CCCC1)N1CCCC(Nc2ccccc2)C1
