Task: Answer the multiple choice question.
Query: Which compound has a -1.829% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: CCOC(=O)c1cnc(-c2ccccc2)nc1N(C)C
b: CCOC(=O)C1=C(N)N2C(=O)C(C)SC2=C(C(=O)OCC)C1c1ccccc1
c: Cc1ccc(-n2c(SCC(=O)N/N=C/c3ccc(C)s3)nnc2-c2ccccc2)cc1
d: Cc1ccc(S(=O)(=O)NCCC(=O)OCC(=O)N(Cc2ccccc2)C(C)(C)C)cc1
e: CC[C@H]1OC(=O)[C@H](C)[C@@H](O[C@H]2C[C@@](C)(OC)[C@@H](O)[C@H](C)O2)[C@H](C)[C@@H](O[C@@H]2O[C@H](C)C[C@H](N(C)C)[C@H]2O)[C@](C)(O)C[C@@H](C)C(=O)[C@H](C)[C@@H](O)[C@]1(C)O
Answer: a. CCOC(=O)c1cnc(-c2ccccc2)nc1N(C)C
