Task: Answer the multiple choice question.
Query: Which compound exhibits a 6.501\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a) O=C(CC1(O)C(=O)c2ccccc2C1=O)c1ccccc1
b) Cc1ccc2c(CN3CCCc4ccccc43)cc(=O)oc2c1C
c) COc1ccc(N2CCN(C(=O)c3cn(C)c(=O)c4c3c3ccccc3n4C)CC2)cc1
d) CCOC(=O)C1=C(CSc2nc(-c3ccncc3)ccc2C#N)OC(N)=C(C#N)C1c1cccnc1
e) CC1=C(C(=O)NCc2ccc3c(c2)OCO3)C2(CCC(C)CC2)OC1=O
Answer: d. CCOC(=O)C1=C(CSc2nc(-c3ccncc3)ccc2C#N)OC(N)=C(C#N)C1c1cccnc1
