Task: Answer the multiple choice question.
Query: Which compound has a 2.775\% 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 CC(=O)c1ccc(S(=O)(=O)NC2CCSc3ccccc32)cc1
b O=S(=O)(NCC1CCCO1)c1cccc(S(=O)(=O)N2CCCC2)c1
c COc1ccc(C2NC3=C(CCC3)C3(C#N)C(OC)(OC)N=C(N)C23C#N)cc1
d COc1ccccc1NC(=O)c1cc2ccccc2o/c1=N\O
Answer: a. CC(=O)c1ccc(S(=O)(=O)NC2CCSc3ccccc32)cc1
