Task: Answer the multiple-choice question.
Query: Which drug has a 1.749\% human ether-à-go-go related gene (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 CN1C(=O)CC(N2CCC(C(N)=O)CC2)C1=O
b CC(=O)c1ccccc1NC(=O)CSc1nnc(Cc2csc(C)n2)o1
c CCOc1ccc(S(=O)(=O)N2CCCC(C(=O)NCC3CCCO3)C2)cc1Cl
d CC(=O)c1ccc(NC(=O)COC(=O)c2ccccc2N=Nc2ccc(N(C)C)cc2)cc1
e C[C@@H](C(=O)Nc1cccnc1)n1c(=O)[nH]c2ccccc2c1=O
Answer: a. CN1C(=O)CC(N2CCC(C(N)=O)CC2)C1=O
