Problem statement: Answer the multiple choice question.
Question: Which compound has a 0.821\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a: CC1(C)CC(=O)C(C(c2ccco2)C2C(=O)CC(C)(C)CC2=O)C(=O)C1
b: CCCC/C(O)=C1\C(=O)CCCC1=NCCc1c(C)[nH]c2ccccc12
c: Cc1ccc(-n2ncc3c(NNC(=O)c4ccco4)ncnc32)cc1Cl
d: CC(C)c1ccc(CCNC(=O)c2ccc([N+](=O)[O-])cc2)cc1
e: Cn1c(SCC(=O)NNC(=O)c2ccccc2)nnc1C(F)(F)F
Answer: b. CCCC/C(O)=C1\C(=O)CCCC1=NCCc1c(C)[nH]c2ccccc12
