Task: Answer the multiple-choice question.
Query: Which compound has a 13.969\% 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] COc1cc(S(=O)(=O)N2CCOCC2)ccc1NC(=O)COc1ccc(N(C)S(=O)(=O)c2ccc(C)cc2)cc1
[b] O=C(NCCc1ccccc1)c1ccccc1SCC(=O)N1CCCC1
[c] COC(=O)c1cc(S(=O)(=O)N2c3ccccc3CC2C)cn1C
[d] COCCCNC(=O)/C(C#N)=C/c1c(N2CCN(C)CC2)nc2c(C)cccn2c1=O
Answer: d. COCCCNC(=O)/C(C#N)=C/c1c(N2CCN(C)CC2)nc2c(C)cccn2c1=O
