Task: Answer the multiple choice question.
Question: Which compound has a 10.805\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
[a] O=C(NCCCn1ccnc1)/C(=C\c1ccc(Br)cc1)NC(=O)c1ccccc1
[b] CCCC(O)(c1ccc(OC)cc1)C(CN1CCOCC1)c1ccccc1
[c] CCC(=O)n1cc(C2OC(=O)C(C)(C)C(=O)C2(C)C)c2ccccc21
[d] O=c1[nH]ncc(N/N=C\c2cccs2)c1Cl
Answer: d. O=c1[nH]ncc(N/N=C\c2cccs2)c1Cl
