Problem statement: Answer the multiple choice question.
Query: Which drug has a 19.020\% 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] CCOC(=O)Cc1nn(C(C)C)c(=O)c2ccccc12
[b] COc1ccc(C(=O)Nn2c(C)nc3ccccc3c2=O)cc1
[c] Cc1cnc(NC(=O)CSc2nnc(N)s2)s1
[d] O=C(CN1CCN(Cc2ccccc2Cl)CC1)N/N=C/c1ccco1
[e] CC1CC(C)CN(C(=O)Cn2c(=O)n(CCCCC(=O)NCc3ccco3)c(=O)c3ccccc32)C1
Answer: a. CCOC(=O)Cc1nn(C(C)C)c(=O)c2ccccc12
