Task: Answer the multiple choice question.
Query: Which compound has a 5.773\% 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 other words.
Options:
(a) CCc1c(C)nc(SC)n(CC#N)c1=O
(b) O=C(Nc1cccc(NC(=O)c2cccs2)c1)c1ccc2c(c1)OCO2
(c) C=CCOc1cccc(CNn2cn[nH]c2=S)c1
(d) CCN(CC)C(CNC(=O)CSc1nnnn1-c1ccc(C)c(C)c1)c1ccco1
(e) COc1cc(C2C(C#N)=C(N)OC3=C2C(=O)CC(C)(C)C3)ccc1OCCN1CCOCC1
Answer: a. CCc1c(C)nc(SC)n(CC#N)c1=O
