Task: Answer the multiple choice question.
Query: Which drug has a -77.576% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
[a] O/N=C1/CCc2nonc2/C1=N/O
[b] CCCCNC(=O)c1cc2c(=O)n3cccc(C)c3nc2n(Cc2ccccc2)c1=N
[c] O=C(OCc1ccccc1)c1ccc(Br)o1
[d] O=C(NCc1ccco1)C1CCN(c2nc3ccccc3n2Cc2ccccc2F)CC1
Answer: b. CCCCNC(=O)c1cc2c(=O)n3cccc(C)c3nc2n(Cc2ccccc2)c1=N
